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.

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. -- mr_bill mr_bill's Profile: http://forums.slimdevices.com/member.php?userid=6737 View this thread: http://forums.slimdevices.com/showthread.php?t=49041 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] power supply upgrade for duet receiver
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. - Ken (hearing differences where they shouldn't exist) -- Rodney_Gold Sb3/Z-sys RDP1/meridian DSP5500's TP/X-cans v3/Senns 650's TP/TACT 2.0/SCM 50a's TP/Meridian DSP5000's "The nicest thing about smacking your head against the wall is...the feeling you get when you stop" Rodney_Gold's Profile: http://forums.slimdevices.com/member.php?userid=14618 View this thread: http://forums.slimdevices.com/showthread.php?t=49041 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] power supply upgrade for duet receiver
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!

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. -- iPhone *iPhone* 'Last.FM' (http://www.last.fm/user/mephone) Media Room: Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono Blocks, Vandersteen Quatro, VeraStarr 6.4SE 6-channel Amp, VCC-5 Reference Center, four VSM-1 Signatures, Runco RS 900 CineWide AutoScope 2.35:1 Living Room: Duet, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Bedroom: SB3, NAD C370, Thiel 2.3 Home Office: SB3, Parasound Vamp v.3, VSM-1 Sigs Mobile: SB3, Audioengine A5 iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=49041 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

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.
