The issue is that more amps for cheap is a bad bad way to go. These cheap higher amp Power Supplies are not isolated supplies and cause more problems. If you are going to get another wall wart type supply, order the newer version from Logitech. If your going for 3Amp or more, pay the big bucks and get a linear supply. It will not improve anything on you unit, but it also will not add any bad problems or hum! Most of the higher amp wall wart 5VDC units were not designed to run audio gear or DACs so no care was taken for isolation to prevent hum and nothing is done to eliminate RFI and EMI produced by the switcher. If your looking to down grade your SB and your audio experience, then by all means get one of those 4 amp Power Supplies. -- 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
