[SlimDevices: Audiophiles] Squezzebox 3: power supply recommendation. other tips?

[brjoon1021]

Hello,

i have had m y system appart for years... long story.
Now that I am putting it back together I have found that I have no power
supply for my Squeezebox 3. I need to buy one. Do you have any
recommendations on what to buy ? I am sound conscious or I would not
have posted in this subsection, but I don't want to spend over $50 at
most.

Are there any 3 rd party sofware or settings that might wring the last
bit of sound quality out of my SB3 ?

Thanks !

Hi Ronnie!

And when you've done the Otex trip, a nice hot soak in a whirlpool bath
followed by a careful alignment of your head with the neck jets is a
great way to do a DIY ear syringe (it's a lot gentler than getting some
busy nurse to do it, lol... ). ;)

I have an Allsop lens cleaner with a number of sound check tests on it &
I was pleasantly surprised to discover that I could still hear the
highest note on the sweep test - it comes on immediately after the nice
lady stops talking, so it's definitely the top one. It doesn't say
exactly how high it is, but I would guess around 16kHz, it's a very high
whistle. All the frequencies came out at the same subjective volume
except a low one which was louder. I imagine that one hit the resonant
frequency between my concrete floor & concrete ceiling about 8' above:
so my next project is to make some stands for my subwoofers to decouple
them from the floor! Btw, I'm 63 now & had expected my HF hearing to
have gone the way of all flesh by now...

Clean ears is definitely the way to go if you want clean sound!

I doubt if buying anything more expensive will get you any more sound
quality. In fact, I'd lay money on it.

Any low noise switching power supply with proper specs IE 5V DC
regulated, Center positive, sleeve ground Connector: 2.5mm ID, 5.5mm OD,
11mm long Min supply rating: 1000mA. So as long as it outputs 5VDC with
at least an Amp of current and is properly filtered (low noise) it will
work just fine.

The only thing better (and only slightly) is using a 6VDC battery with
10Ahr capacity or better which you would recharge over night after use
(or as need be dependent on use). The slight advantage is it is
absolutely clean DC power with no noise. Hence it is impossible to pass
power supply or mains noise through to the SB3. I have a battery
operated Pre-Amp that sounds just as good as a passive Pre-Amp but I
doesn't lose the gain of an active Pre-Amp with the battery powered
Pre-Amp. It has two batteries so one can be charging while the other is
in use.

Hi iPhone! (on a different thread, I'm still absorbing the Vandersteen
links you sent me, lol... )

I use a LiFePO4 rechargeable golf cart battery (24AHr, rated for 30A
continuous, 90A peak) to power my Mytek Brooklyn external DAC which has
a nominal 12V DC input - obviously you have to disconnect the mains AC
input.

The battery has 4 cells each with a nominal 3.2V output, so overall it
supplies 12.8V nominal. But in fact any power supply in the 7-14V DC
will suit the Mytek, it's the current capability rather than the voltage
which is most important, for solid-state electronics at least. However,
with that much current capability it *-is-*
absolutely vital that you wire it up with the correct polarity!!

I have failed to find a 2.5mm DC power plug rated at more than 5A, but
the point of the high current capability is entirely to handle
transients - the average current consumption of my Mytek at 12V (or so!)
is well below 1A, so there is no real risk of melting a correctly
connected plug: the consequence of getting the polarity the wrong way
round around WOULD be a little more severe for my DAC. Rather than use a
fiddly soldered plug, one can readily obtain 2.5mm DC power plugs from
eBay with screw connectors *-&-* the +ve & -ve inputs clearly marked.

My golf cart battery can be fully recharged in 6 hrs using the supplied
trickle charger. I use an electronic timer to switch the charger off, &
position the beastie under my kitchen extractor whilst it's charging
overnight just in case, although it is a sealed unit & according to
Wikipedia LiFePO4 batteries are the safest type of Lithium ion
batteries.

As you rightly say, you can't really beat native DC: & it cost less than
half the price of the sexy mains-driven power supply that the dealer was
-very- keen to sell me...

My problem with the cheap PSU's is the failure rate. I went through
three of them in a year, and I finally decided to just take the Classic
offline and went with a Pi device.

When I was looking at options, I came across this, and people who seem
to know what they are talking about were very high on it:

The price is reasonable compared to others, and I know allegations about
improved sound quality are debatable, but maybe it helps answer your
question. I didn't buy one so I have no personal experience. Maybe
others here do.

Completely and totally agree. The stock PSU has utterly sucked in my
experience. In my environment it quickly impairs remote operation. Hence
I also bought an "improved liner" power supply, and been trouble free
since.

The original 230v SB3 supply was ifyllda qualitywise , but later modells
of SB3 with logitech branding got a similar supply to the Touch . So get
the same supply as a squeezebox Touch ?
