I'm not sure you intended those two criteria to be in a particular
order, but in case anyone infers the wrong thing from "the second
being...", I'd have to point out that the voltage is the MOST important
part if you don't want to damage the powered device.  A power supply
with too high a voltage will likely damage the device being powered,
whereas a power supply with too low a current rating will simply mean
that the device will not function with that PSU.  At worst, the PSU may
be damaged, but the powered device will be not be harmed.

Sorry for being a pedant!

You may need an upgraded linear power supply but you definitely do need
an external dac to improve the sound.  I tried my older SB3 analog out
versus into Benchmark Dac 1 a few years ago and the SB3 needed to go
into the dac to improve the sound.  Linear supply is another matter -
the differences with a cheaper power supply are not that great in my
experience.

I found a difference in sonics when I changed the place the flac gets
decoded from my TP/SB to the puter? Its a cheap tweak for sure - it's
free


Quoted from the thread

You can try disabling the native FLAC streaming and let the server
decode the file and stream WAV. If this changes things you'll fall into
the "I hear a difference where one shouldn't exist" camp. There are a
bunch of folks that belong to this :).

1. SqueezeCenter Settings -> Advanced -> File Types -> FLAC/FLAC =
disabled, FLAC/WAV = flac
2. Flip to another song and start playing. If you're using Windows, you
should see a process labeled flac.exe in the Task Manager indicating the
server decode is operating.

iPhone, Thanks for the detailed response. Where did you find the current
spec for the Creation Audio supply? I couldn't find that anywhere
online. I am aware that the SBR expects a minimum supply rating of 550
mA.

As to my interest in upgrading the power supply:

Just got the Duet about a week ago. I have added it to my main rig, and
while I love the convenience of the system, the sound leaves something
to be desired.

The main rig is: Music Reference RM5 Mk III tube preamp -> McCormack
DNA-1 Rev A power amp -> B&W Nautilus 805 speakers. Cabling is Cardas
and Synergistic Research. AC Power is via a dedicated line, distributed
through a Furutech eTP-80 (except the power amp plugs straight into the
dedicated AC line).

My digital source has been a Marantz DV-8400 Universal Disc player.
Power to that is through a JPS Digital Power Cable. The Marantz sits on
Aurios bearings.

My discs have all been ripped with dbpoweramp CD ripper to FLAC. Played
back via the SBR through the main rig, compared with the same discs
through the Marantz, the sound is thinner harmonically, and the imaging
is less distinct. It is NOT bad, just not as good as what I'm used to.

Which leads me back to the notion of upgrading the power supply. I
would expect that putting a nice DAC in the chain would be much more
effective, but I don't have the funds for that at present. I have
gotten lots of mileage from various cheap tweaks in the past, and am
just looking for one more!

Thanks for your thoughts,
Earle

Hello Earle, 

One of the most important things about a power supply for an audio
device is available current; the second being the output voltage is in
the ballpark. A regulated supply is always a nice bonus. The link you
published should NOT be used with an SBR. That $10 PS is totally
inadequate. Its maximum available output current is 250mA, which is
well less then half of the required minimum!

Not putting to fine a point on it, if one doesn’t know the
minimum power supply requirements before attempting to replace/upgrade
the OEM PS the previous post advice about quitting while one is ahead
is excellent advice. IE, you are better off with the proper OEM Power
Supply.

Besides before spending money to upgrade the OEM supply, does your
system not need upgraded first to take advantage of bothering to try to
improve the output of the Duet with a PS upgrade? Not knowing your
equipment, how about a DAC, new speakers, better pre-amp, amplifier
with more current? Unless all of this is already top shelf, not much
need or use in a PS upgrade for the SBR.

Tyler, my SBR power adapter label reads  "output +9.0v". I am hoping to
find a linear supply for the Receiver only. I came across this one that
looked promising, and cheap:

http://shop.creationaudiolabs.com/product.sc?productId=27

Thanks for the Herbach link, but I didn't find any 9v linear supplies
there.

Quitting while ahead is generally good advice. I never seem to do it
though.

Here is where you can find low cost power supplies:
http://www.herbach.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=HAR&Category_Code=PWS

If you don't know how to select among them, upgrading the PS is not for
you.  The wrong one may destroy your SBR.  Quit while you're ahead.

Yep. Seems odd as there are lots of posts to the forums about budget
power supply upgrades for SB3, etc. Is the Duet Receiver that
different?

Judging by the number of replies, it looks like you will need to do more
