I've used a couple of switch mode psu units....in my system in the past and I've never really felt comfortable with the results ...they seem to leave an edge to the music ..difficult to describe.
I've gone back to linear types and found these more forgiving [?] or more musical ....the latest unit is a simple voltage regulator and bridge with 15000uf of pana fc smoothing caps and a toroidal transformer rated at 75va 9-0-9, I've also used a schafner iec mains filter and fused switch . This is a small step up from the square frame tranny version with 10,000uf. Once the psu board was placed in it case there were more small improvements, as I isolated the board from the case on a layer of sorbthane like material. The case is built round a granite sheet using 45mm x 15mm wooden sheet and an 18mm mdf lid..the whole weighs in at 5kg and acts as a vibration sink. this will be my last psu for a bit as I've exhausted my current ideas -- zanash Acoustician and builder of interesting cables ------------------------------------------------------------------------ zanash's Profile: http://forums.slimdevices.com/member.php?userid=12157 View this thread: http://forums.slimdevices.com/showthread.php?t=38271 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
