TAS just published a review of the Sony HAP-Z1ES player. (I'm sorry, but
I don't know how to post a link). Plays all sorts of formats and comes
with a 1TB internal drive. Sounds like an interesting unit, tho at over
$2000 I won't be getting one very soon. :-)

I found some of the comments quite amusing, even endearingly clueless.

Very pricey for what you get. I have a TB hard drive in my little
FitPC2 music server; aside from once having to install a bigger hard
drive (which the end user is able to do, unlike on the Sony), it's been
trouble free for years. Adding a Touch gives me a more robust
equivalent to the Sony at a fraction of the price (assuming one could
find a Touch). There is something to be said for a simple stand-alone
unit, but there is no capacity for multi-location play, aside from what
you could do with a receiver.

But it can play DSD files!!! And it has a control app!! Plus it is a
great value:

"A Mac Mini with monitor, keyboard, mouse, and external drives attached
to the MyTek Stereo192 DAC runs over $2500, and if you use better
quality cables the price could go substantially higher. Even the Sonos
ZP100/ Mytek Stereo192 front end costs around $2300 when you include a
NAS drive. For $1999 the Sony HAP-Z1ES supplies the computer, hard
drive, DAC, and app to run it all."

Did I mention that it plays DSD files? :) ;)

Do I detect a small amount of sarcasm there Ralph? :)

Nice looking I guess. But it does seem a tad pricey to my eyes.

Sarcasm?!?! I could I possibly be sarcastic about something that plays
DSD files?

Then what - the Sony plays DSD files - isn't that enough?

To answer my own question - just playing DSD is not enough - the Sony
not only plays DSD files but it converts everything, as in any analog
input and any PCM input, to DSD and then plays the converted DSD files!!

I must say that I'm impressed with all these advanced features!

1. The HAP-Z1Es also includes Sony’s new “DSD Remastering Engine", which
according to Sony “combines a high-performance DSP (digital signal
processing) and FPGA (field-programmable gate array) to convert *any
signal* into DSD128 signals", as ralphnj already has noted.

2. For compressed music files Sony has developed DSEE (Digital Sound
Enhancement Engine) technology, which restores upper frequencies and the
“tail” of waveforms that were truncated by lossy compression schemes.

The first feature is actually possible to disable and the second must be
pure magic! What's not to like? :-)

Let's take them one by one.

Converting all inputs into DSD - isn't the audiophile mantra supposed to
be the less processing the better? Seems like encoding everything to DSD
for playback adds lots of processing to the signal. But, hey, it is DSD
and DSD is the latest and greatest audiophile buzzword.

Digital Sound Enhancement Engine - this nonsense has been tried before
and each and every time what the fancy given to the process, the process
ALWAYS turns out to be some form of frequency equalization - I'm 100%
positive that Sony's much hyped "Digital Sound Enhancement Engine" is
also nothing more than some equalization. But, hey, it is
DSD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What can I say but mea culpa. Anyway I'm glad that you don't drink any
of the magic audiophile Kool-Aid, which, by the way, is now available in
the new DSD flavor.

Yeah, well. I've been known to knock back a few, but the stigmatic
aftertaste is horrible. Been there, done that, doing it never again!

Yes the aftertaste is awful but the bigger problem is that once the
Kool-Aid wears off you find that your wallet is empty, your credit cards
are maxed out and you can no longer hear the difference between a flac
and a wav file, however the Sony HAP-Z1Es player still plays DSD files,
so all is not lost!

I'd be more impressed if Sony (now Sony/BMG) opened up their archive of
DSD recordings. There are currently only 240 DSD downloads on Acoustic
Sounds, and the majority are the usual Jazz classics. I might even pay
the $25 for yet another version of -Time Out- just to satisfy my
curiosity.

You should realize IF one of these older classics suddenly come out
again sounding much better this won't be because of some magic dsd
transfer cababilities but serious remastering. This pretty most likely
will not happen in pure dsd domain.

Yes that's why I'm not exactly running to the hifi store to get an DSD
DAC :)

Of those 250 recordings , assume that 25 would appeal to my taste .

Sad fact a large crowd of audiophiles buy recordings to listen to thier
equipment not the other way around as it should be .
Only an audiophile could consider buying a new player to listen to 20-40
records .
No these formats will never become mainstream and provide actual music
for a music lover .

The serious remasters could be sold in any popular PCM format ( or
heaven forbid a CD ), but it's not hot stuff for the audiophile crowd
,sadly one boost sales when using a hirez format .

Just think now there is yet another version of Miles Davis' "Kind of
Blue" available - the DSD version available from Acoustic Sounds:

http://store.acousticsounds.com/d/95103/Miles_Davis-Kind_of_Blue-DSD_Download

I'm sure that we will soon see DSD versions for all the usual audiophile
dreck, such as the way over hyped "Jazz at the Pawnshop" and all those
mediocre but well recorded female quasi-jazz singers.

Sure it's dreck but it's DSD!!!!

Does the jump from DSD256 to DSD512 somehow introduce wow, flutter,
surface noise, pops and clicks into the recording to get that real vinyl
sound? Notice I said "vinyl" and not "analog" since with analog the
artifact list would a little shorter and slightly different.

"Because it has been extremely difficult to carry out DSP operations
(for example performing EQ, balance, panning and other changes in the
digital domain) in a 1-bit environment, and because of the prevalence of
studio equipment such as Pro Tools, which is solely PCM-based, the vast
majority of SACDs — especially rock and contemporary music which relies
on multitrack techniques — are in fact mixed in PCM (or mixed analog and
recorded on PCM recorders) and then converted to DSD for SACD
mastering."

That's probably true, but I admit to a fetish for having things in their
original format if available. If the DSD version is better sounding
because of more careful mastering, I don't see that the format matters
much, apart from the premium surcharge (I also admit to being a sucker
for a promise of a "new and improved" mastering of one of my favorites.)
And I can always convert it to 16/44 PCM later.

Just wishing they could document the pedigree of thier recordings a
little better .

Especially the analog side if doing an old recording tape does not
always age well .

So given a good 15 year old digital transfer of a cherished analog gem .
Vs a new as good as it gets Digitla transfer , its no saying which ones
win? has the tape been well preserved or has it aged so much that
difference between old digital and new digital tech is unimportant ?

Would they rather remaster from an old digital source ? Who knows .

They are very for producing new versions for us suckers , but do they
ever consider if it's any piont with it in the first place ?

Personally I'm done with the n'th version of the classics do we need
20th 30th or 40th anniversary versions of everything ?

Oh btw is there any Pink Floyd yet :)

I should have been more clear. If something of these old tapes sounds
really good after remastering it had been PCM already because there are
not many things working directly in dsd at restauration worklow.

No, I got that. But these technical details don't aren't always
determinative at the ear end. It's all a bit academic at the moment as
there are maybe a handful of DSD downloads that may be of interest to
me, particularly at the prices asked.

Just came across this thread and it is amazing. A raft of comments
putting down a product none of you have heard and clearly know little
about, and also denigrating DSD, which apparently, at least the majority
of you have never heard. Sorry, but the height of close-mindedness.

A few points in response to the thread:

1. I own 2 SBT's and a fit pc. The Sony is much better sounding. No
comparison. So for your $2000 you get a much better sounding player and
DAC, plus 1TB of built in storage. It's extremely well built, with high
end parts and very solid construction. Not plastic. Not a bad deal at
all, relative to it's actual competition. Obviously, with a $2000 price
tag, it isn't intended to be a mass market item and isn't intended to
compete directly with a product like the SBT. In "high end" terms, it
can certainly be seen as a good buy.

2. The HD of the Sony can be user replaced, and with a much larger one.
Not a problem at all. It can also play from an external USB drive.

3. There are something close to 2000 native DSD recordings on the
market, if you count SACDs recorded and produced with native DSD. Yes,
mostly classical. Several thousand other SACDs of good analog recordings
converted to DSD/SACD, music of all types. More and more of this is
being released as DSD every day. Lots of people are ripping SACDs these
days, and you can even have it done for you. So not a true obstacle. In
spite of what you may think, there are lots of people with large SACD
collections. So a device like this is quite useful for them. BTW, if
you haven't heard a native DSD recording of acoustic instruments, you
might be amazed at how good it sounds. I have a couple of native DSD
orchestral recordings that simply are the best sounding recordings I've
ever heard of a symphony orchestra. Period.

4. DSD is a fantastic medium for digitally archiving analog master
tapes. I have several such DSD albums and they generally are the best
sounding version, even in some cases better than hi-res PCM versions.
This might be due to better mastering, or it might be that DSD is simply
better at capturing the sound of analog tape. In the end, the format
isn't important, getting better sounding music is. So the fact that a
lot of "Old" rock, jazz, and classical is being remastered to DSD is
only a good thing in my eyes. No one is making you buy remasters if you
aren't interested. I happen to like having better sounding versions of
albums I love. Many (not all) of the remasters I've bought in the last
few years (both PCM and DSD) sound better than the vinyl or CD versions
I previously owned. I'm glad to have them.

5. The "DSD engine". Have you heard it? Take a listen or look online and
see reactions/reviews. I haven't read any actually negative ones. The
reactions range from "it sounds fantastic, I'm doing all my listening
this way" to "I prefer it some of the time, not all". Is there something
wrong if people enjoy the sound of it? Find a system that can upsample
and play some of your favorite recordings as DSD. You might like how it
sounds.

Come to think of it I have never heard any of the expensive USB cables
so often praised in high end audio magazines but you know what that
doesn't make them any less of a rip off. I don't believe that anyone
writing on this thread believes that the Sony unit sounds "bad" rather
we think that the Sony unit sounds quite good we just don't believe all
the marketing BS that comes along with it. And marketing BS is all it is
- the so called "reviews" are merely the Sony press release (pure
marketing BS) simply reworded, along with a nice lunch or dinner from
the Sony advertising rep thrown in.

And in case you haven't been following along at home, EVERY single
music/media streaming device which relies/relied on DLNA fails. So if I
really wanted to buy the new Sony player all I have to do is wait a few
months and buy it at a discount once it too fails and is discontinued.

To you. How do you know that it will be better sounding to anyone else?

BTW, if you haven't heard a *good* native PCM recording of acoustic

Such as pretty much any modern DAC.

Interesting comment Firedog. I have not heard the Sony but will
certainly give it a try when I'm next at the dealer.

As one who has been buying SACDs since about 2001, ripping my SACDs
since 2012, having played with PCM --> DSD conversions like with JRiver
upsampling, and have some experience with the whole PCM <--> DSD
conversion process (see the 'post on my blog this week'
(http://archimago.blogspot.ca/2014/04/analysis-comparison-of-dsd-encoders.html)),
I personally do not feel DSD adds anything special to sound quality. A
well done 24/96 (especially multichannel!) is as good as anything I've
heard from DSD over the years...

As suggested by the conversion results on the blog post, I'm quite happy
with 24/88 conversions of DSD64. Accuracy is excellent so the math is
good! In fact, mainly for convenience and space savings, I only bother
keeping about 20 of my SACDs as DSD on my server mainly as demos for
friends who want to have a listen. The rest I keep as 24/88 for
streaming to the Transporter.

I suppose one could argue for the high sampling rate of DSD (temporal
resolution of things like impulse responses) and filter difference, I'm
not one who has experienced or believe that they make much difference
ultimately compared to a good upsampling linear phase PCM filter.

Can you tell us which recording you're referring to here? I would
certainly love to have a listen... Maybe even try resampling to PCM to
see whether I hear a difference.

Good blog again .

Have you investigated DSD > PCM conversion , as DSD has less resolution
than PCM i see no loss of anything ,but are there other factors I do
think a 24/88.2 pcm of any DSD will be transparent to any human .

I'm not in any way a believer in DSD (all arguments for its existence is
moot since hirez pcm recording came to be ) , but lets for discussion
sake pretend that it does somehow makes even better recordings than
24/192PCM presumably as DSD128 , or heck just equally good would suffice
for my point .

Then we are back to to the usual confusion about recording formats and
consumer playback !

RECORDING IN DSD128 (FOR EXAMPLE ) DOES NOT MAKE IT NECESSARY TO
PLAYBACK IN DSD , JUST AS RECORDING IN 24/192 PCM DOES NOT MAKE IT
NECESSARY TO PLAYBACK IN 24/192 PCM

These are not even related questions anymore !

They where related in the past , CD was necessary as we had no digital
carrier format at all at the time . But now we have several formats
that’s surpass human cognitive ability to chose from .
In the days of SACD and DVDA they where more or less artificially
separated by marketing (and most recordings are/where fakes anyway ) a
recording in any of those format could be used to produce any media .
And no one had rips or files as we have today.

I think some DSD recordings would just make great CD's or Hirez 24/88.2
flac files for us consumers btw .

Thats why this is so bizarre , just because some studios have got to
their minds to release DSD -files- to consumers (they should just have
released records in other known well known formats )does not necessitate
a end to end DSD playback chain ? Thats why this just reeks of marketing
woo woo . The early successes if vitalizing the media market by CD and
DVD makes it tempting to try again with yet another new format , but
there where real reasons for CD and DVD they replaced horrible formats
there is no cause any more .

And that it makes for another redundant and expensive format for the
industry to handle is another topic .
My pow is as always that we already have all formats we need for music
and possibly much more formats than we ever need. To many file formats
is also just confusing who ordered that :)
If that’s going to change it's must be something thats makes it less
complicated and provide something else to the experience .

I don't have any real argument for you except what I hear. I hear a
small improvement with native DSD and with DSD over hi-res resamples to
PCM of DSD. It is possible that this is simply my DAC being better at
converting DSD, although I don't think it is only this, as I have heard
it under different circumstances.

DSD sounds different. I am far from the only one who thinks so. To some
ears it is better and more analog like, to other ears it is "Soft". We
can agree to disagree on that, it is a matter of taste.

As regards a player like the SONY that upsamples PCM to DSD, again,
sounding better is a matter of taste, not ideology. You can make
whatever argument you want, if some people think it sounds better, then
I think that's great for them. The argument is no more useful than
whether tubes sound better than SS or are euphonic distortion, or
whether vinyl sounds better than digital. Basically a useless argument,
whidh cannot be won.

Your argument about too many recording/playback formats is a good one.
It may be the reason DSD doesn't really succeed.

Good discussion boys and I don't think there is a need to fight over
this either... Whatever works is fine. High-res formats are already
capable of retaining accuracy enough for anyone's needs and the
limitations of the recording studio. The issue here is nothing even
close to measurable and audible differences between digital vs. vinyl!

I agree with keeping the original modulation technique - Channel
Classics albums started life as DSD with minimal studio manipulation I
am told, so I'm happy to keep a copy as DSD files in my archives since
that's the best they get. Based on objective measures though, I feel no
harm was done when converted to 24/88 for the DACs that cannot handle
DSD so I have that version on my LMS server as well (the PCM version
also has the benefit of digital room correction).

I think Mnyb has a point with too many formats though... It just
fragments the market, confuses the consumer, and creates unnecessary
disappointment. Despite the advertising push into high-res "HRA", I
truly feel that there's just not going to be much of a market because
the average consumer will not hear a difference and move along... This
is *nothing* like the obvious benefits of DVD vs. Blu-Ray if people are
searching for an analogy. With a small consumer base (ie. obsessive
audiophiles who want the best version of their favourite album), it
makes sense to aim for standardization.

Yeah theoretically you may loose something when changin modalation
format in practice not soo i think ?

I'm actually going to try one of their recordings ,just for kicks . The
recording quality I just bluntly assumes will be retained in whatever
format :)

I'm a firm believer in good recording quality anyway , lets see if there
is a recording that makes musical sense there.....

Another issue with DSD is that it assumes and old fashioned hifi where
you as quickly as possible convert to analog ( the wrong aproach imo )
.
No dsp or eq or room correction or loud speaker crossovers are done in
native DSD .
So post processing in you home hifi is going to be PCM anyway .

Same for studio equipment and stuff DSD is just odd ?

I do think there are equipment that favors one format over another .
The practical aproach would be to use whats works best in that situation
.
I think archimago has some measurments with weird results for different
formats ? in some of his dacs ?

The overwheling issue is the recording itself , format DSD vs PCM vs CD
is almost completely irrelevant in the wider scheme of things

I think archimago has some measurments with weird results for different
formats ?

Channel Classics has some great sounding native DSD recordings. They do
minimal processing, I think there is only a PCM conversion at a few very
small edit points. Other than that, the original native DSD remains. If
you like Mahler, try their Mahler 1st I linked to earlier.

I believe if you use HQPlayer all sorts of manipulations of DSD are
possible.

I'm going to have to convert to PCM for my eqipment anyway .

My processor works in PCM and the digital xover in my speakers does too
, foobar2000 has a plugin I think .

I remember JA of Stereophile writing that a big problem is that we
measure what is easy to measure, rather than necessarily what's
important.

I think measurements of sine waves (or two sine waves for IM distortion)
is a pretty limited measurement. It is what it is, a minimum test. The
behaviour of the device with a real music signal might vary
considerably.

The old principle - one often quoted when it comes to business metrics -
"you get what you measure". If designers design to perform well with
these sine wave tests (whether because they trust them, or they are
fighting a spec war) then the design will perform well with said sine
waves.

I would very much like to see a new set of standardised tests which can
really represent a rich, complex signal in a meaningful way.

Anyone got ideas? Archimago, this could be your chance. The "Archimago
Test" beckons!

That rich, complex signal will consist of a sum of sine waves.

Here in the USA we are quickly learning that the old adage quoted above
also applies to education. By basing so much on a few standardized tests
we are discovering that teachers simply "teach to the test", students do
well on the tests and learn basically nothing useful.

Ralph, exactly.

Julf, yes it's a sum of sine waves (kind of, for the purposes of this
discussion) but where do we actually test a sum of sine waves? My point
is we test one, or maybe two, for most of the tests we set store in.

Although the sampling theorem is proven and perfect, we know real
equipment isn't. It isn't perfectly linear, it doesn't have
instantaneous infinite power available etc. All I'm saying is that it
might be an assumption too far.

To be fair, JA tests gear on a regular basis so his comments should be
taken seriously. I don't believe he's a raging subjectivist, by any
means.

JA is whatever the advertisers want him to be, i.e. if their equipment
tests and measures really well then JA is a objectivist but if their
equipment equipment tests and measures really poorly then JA is a raging
subjectivist. Therefore NOTHING JA says or writes can be taken even
remotely seriously. The only difference between JA and Robert Harley at
The Absolute Sound is that JA publishes measurements otherwise both of
them are available to the highest bidder.

When testing for intermodulation. Two is "many", any additional ones are
just extension of the same model.

A single sine wave test reveals non-linearity, a two-wave test reveals
intermodulation effects. What additional things do you think a third or
257th additional wave would reveal?

Real equipment will obey the mathematical equations - the only question
is if our equations are complete and sufficient. Neither the sampling
theorem nor the fourier series (the transform is a mathematical tool)
assume (or require) "perfect" equipment.

Semantics, but of course the maths stands regardless of physical
equipment. The question is if the physical equipment conforms to the
maths perfectly, given it isn't perfect.

Julf wrote:

So you say, but why is this not an assumption?

As for two sine waves for IM, are you saying that ANY two frequencies
tells us ALL we need to know about the devices IM distortion under all
conditions? How can you assume there aren't frequency-dependent
characteristics? Level-dependent characteristics?

Trying the channel classics shopping experience .

Some observations , a bit geared towards audiophiles , the are using
"van den hul cables" for example and they shills some jplay and other
myth driven software ,which pretty much does away with any technical
cred they might had .
So i wont buy into anything they say about DSD .

Slow horrible java driven downloader !? thats 1/smart . whats wrong with
rigth click and save a zip file ,why make something incredible simple
convoluted .

Never the less they may still make decent recordings , professionals are
not imune to audio voodoo either , but it may not stop them from making
good records lets see and hear some of the stuff first .

And thier studio equipment is also custom stuff ,but equipment with a
certain character of thier own is used as a tool by many pro's thats
fine with me it can be a part of the creative process .

Intend to sample some more stuff . if it makes musically sense to me I
can tolerate some idiosyncrasies , even established vendors makes things
hard too sometimes .

Hopefully they are not as bad as other "audiophile labels" :) but their
chosen genre makes it easier . the usual mo for audiophile labels is
often excellent recordings of "meh" artist you never heard of ( and
probably should not hear, if where not for these audiophile labels ....
)

Wonder why not classical orchestras or artist uses Bandcamp more often
it would work very well ?

Great discussion guys...

I agree with Mnyb around the topic of measurements. Diffmaker
comparisons which null out pretty much tells us if there's any
difference at all. As for the idea of needing more and fancy tests,
well, of course there could be things to try... For example, on my blog
there's a suggestion to try 2fs (ie. 96kHz) jitter tests as opposed to
the standard 24-bit/48kHz one I'm using currently.

Hey, I'm sure that will show significant differences between DACs at
24kHz! Maybe a dog/cat can appreciate jitter up at that frequency... The
poster suggests that this makes an audible difference with 24/96 music.
I already have the test signal to do this but have not tried yet so will
withhold judgment.

Ultimately, it boils down to audiophiles (and the press) accepting that
if we're really going to get anywhere, double blind listening tests are
essential. Yet no magazine does this. If anything, audiophiles look for
every possible angle to "debunk" or "invalidate" testing which is
acceptable to every other scientific discipline I know of that deals
with human perception or biological effect. Show me double blind test
results where listeners are able to discern differences between DACs,
cables, etc... AND where standard measurements cannot explain these
differences. Then we can at least consider what other tests need to be
devised because then we can say with some certainty that "we're missing
something".

---

Ralph:
I think you're right about the assessment on JA. While I appreciate his
work on objective measurements, there is at times a clear bias as to how
he interprets the results. Mediocre results from an inexpensive / not
well regarded brand will get used to explain inadequacies. Mediocre
results of expensive / well regarded brand / well advertised products
often gets tossed aside as "I can't explain why Mr. Subjective loved the
sound... Perhaps it's exactly because it measures like this!" (For an
example, have a look at his conclusion of Audio Note's CD-4.1x CD player
- awful noise floor, waveform reproduction, even terrible jitter.)

JA is a businessman after all... Yes, always worth reading these rags
with this fact in mind.

Yes, Channel Classics is deep into the audiophile hardware kool-aid.
However, the recordings are still good and I can enjoy both the DSD and

Funny thing was about a month ago I E-mailed them that the 24/192
version provided no benefit due to use of Saracon (which they confirmed
they used). The proprietor still felt 192kHz was "better" despite the
lack of any content >48kHz. Oh well...

Yes i bought the 24/96 version if the mahler no 1 . I read that they
used saracon ( weis ) so they make "better" transcoding than I do
,wonder why not 24/88.2 ?

I have yet to listen to,it as it took,so long to download .

Did not now about the 48k limit of saracon but it makes very much sense
as DSD has so much ultrasonic noise higher up so you actually don't want
higher fs so I usually don't buy transcodes of DSD at 24/192 is there is
a risk that noise is actually encoded as signal !!

And as I understands it if a DSD DAC encounters a DSD signal,it may
employ proper fillters against the ultrasonic noise ,there is a spec for
SACD at 30k with some slope for its DSD64 .

If a 24/192 signal has encoded DSD noise as signal the DAC would not
know ? Wonder how HD tracks does when they actually sometimes rip SACD
for their 24/192 files ;) .

A tech note :
If the signal is really without any content at all above >48kHz 96k fs
would really capture everything there is , aka the Shannon nyqkvist
sample, theorem .

OT about classical music:
A questions to classical music buffs out there ?

Does channel classic makes sense as classical label ? Are the artist and
orchestras recorded that good ? Or should I on musical grounds look for
another interpretation of for example Mahler first symphony ?
But don't spam to much I know that you dudes usually have >100 versions
of every major work just for thier different takes of the music .

Yes Fourier was not wrong , every signal can be represted as a sum of
sines .

besides prioties :

*1. Do away with sigthed testing , estblished some kind of controlled
protocoll (ABX) .* (1b . You may not need extended bettter measurments
if something fails an ABX .)
1C also ABX against a reasonable standard , obviusly coulored stuff is
not hifi .

2. -Then- residual unresolved differences may need better measurment ( a
couple of percent % for electronics ) Spekaers may be beyond a magazine
to thoroughly measure ,according to Harman it takes 70 different
measurments to fully characterise a speaker 8Sean Olive).

3. There is a very good test audiodiffmaker , you can compare a complete
song how complex do you want :) choose whatever music you please .

Difference test is really good , then you can actually adition the
leftovers seprately .

Then we have the stuff thats not meant to be transparent . it will fail
all the tests but a diff measurment could shead some ligth how that
components particular euphonics works .
Maybe even publish files for curius readers to download .
Some people want a certian tonality thats not neutral .
But it would be more honest to admit what it is and not invoke magic or
" the unknown " .

It has been proven many time that there really is no unknown .

TAS for example uses some kind of very contorded reasoning to avoid ABX
so that they can live in thier illusions (I do suspect they know but
like to keep thier readership in the cult )

Just how many pure DSD recordings do you think there are? By "pure DSD"
I mean a recording that was made using only DSD recording and mastering
equipment and an analog recording directly converted to DSD but either
of the following:

1) A digital recording originally made using PCM digital and then
converted to DSD

2) An analog recording converted to PCM digital and then converted to
DSD

This leaves very few pure DSD recordings.

Here is a good article that explains what I am referring to:

AFAIK the Sony isn't a streamer as such, it does have network
connectivity but it only gets used with the proprietary software to copy
files to the internal discs. No streaming other than internet radio.

I stand corrected. Then the Sony player will fail simply because DSD
will continue to be the Betamax of the digital audio world.

Not a good analogy. Betamax failed *despite* being better than the
competition - not something DSD can claim over PCM. (Actually, I suppose
it does *claim* to be better. But that's just a lie).

Dsd is piontless sans sacd discs .

Ergo every product/service relying on dsd nowdays is fluff .

All hirez formats are equally good so whts the piont with special
hardware for a special format ?
When you can convert the files in minutes to for example 24/88.2 flac .

The sony unit itself may produce very respectable sound i have no
opinoin on that because i dont own one.

And if somehow pcm files converted to dsd on the sony sounds different
then its simply broken.

The claim is not that the converted files sound "different" rather the
claim is that the converted files sound "BETTER", whatever that is
supposed to mean (possibly some veil gets lifted or some window gets
opened or the blacks get blacker or the silence gets quieter or the
rhythm gets more rhythm etc. - you know all that typical worthless
audiophile mumbo jumbo).

That's exactly what I mean .

All equipment can do afterwards is making their source sound less bad ,
nothing can sound "better" it can at best not add or distort more .

However what Sony migth have done is a very good product for converting
DSD that is less god at handling PCM .
In an imperfect world it can be that DAC's and similar handle different
formats differently !
But that does not sell product " our products internal signal chain
works better if it's always feed DSD " in the hands of marketing it's
gets turned into "its sounds better" :)

OT my own equipment does have built in sample rate conversion I *think*
it's sounds slightly different ( not dbt yet ) so the effect is not
unknown ,there are probably more examples .

Even more Off topic .

The popular idea of resampling to 24/96-192 on the server IMO only have
3 explanations .

1. Placebo
2. The conversion algo adds euphonics
3. The DAC itself or it's filter works better feed at this sample rate
.

My personal favourite is 2 . Very contorted choice of filter algo
extreme minimum phase filters that actually alters the extension in the
treble audible and that's all we hear .
