The stock supply is best for you and you would hear no improvement by wasting money on a PS upgrade. The SB3 is spec'd for a regulated 5VDC minimum 1 Amp power supply. If you have a true Classic with the Logitech logo on the front, it is more then likely that your unit came with a regulated 5VDC minimum of 2 Amps wall wart PS. More then enough for how you are using your Classic. And even if ones display is at full bright and actively using all the outputs the current draw is just over an Amp 99% of the time. Nobody is going to hear or catch that 1% and beside many owners have the 2A minimum supply anyway. And for all the folks buying after market linear PS for the SB3, I hate to tell you this, but there are switching supplies inside the SB3 after the 5VDC input so why bother. Can an improved PS improve the SB3? Well of course it can because that is always the first place to improve audio gear by throwing more money at the PS section. The problem is the expense and trouble to directly feed the SB3 with the different voltages needed and disabling the on board switchers. So one would need an external PS box with multiple regulated DC voltages, a cable to carry them, and new power connector on the SB3, disable the internal switchers, and cable the separate voltage needs to the new connector. All of this effort, expense, and work for a slight improvement that many people will probably not even hear because there system is not good enough to hear it anyway. And oh by the way, some guy named Sean has already done this and done it so well that the difference can be heard on most systems: It's called a Transporter. Don't waste money adding to the SB3 that is already an above average entry point into the Network Media Player world. I see guys that bought an SB3 and $1500 to $2100 in mods from Boulder, hey a Transporter is only $1999 and no matter what one spends modifying an SB3, its still not a TP at the end of the day. You might ask what my point is, well its two fold. First don't waste your money adding to a product that is already well above average from the manufacture. Second if you really want a Transporter save your money and buy one, don't throw money at another NMP trying to make it a Transporter. -- iPhone *iPhone* 'Last.FM' (http://www.last.fm/user/mephone) Media Room: Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, 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 Kitchen: Squeezebox BOOM Bedroom: SB3, GFR-700HD, Thiel 2.3, Second Boom Home Office: SB3, NAD C370, two VSM-1 Home Gym: SB3, Parasound Vamp v.3, Thiel PowerPoint 1.2 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=59264 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
