I remember a user named iPhone doing ADM measurements on the analog out of the old SB3 using stock or linear psu and the output signal was identical in either case.
No one done that for Touch but I suspect similar results . Some thinker suspect that audibility of PSU is down to it's interaction with the rest of your hifi if your switcher is disturbing amps or DAC for example ? So it's hard to get universal results here, add many cult designers affection for design principles that makes equipment more susceptible to these kinds of problems that would not bother normal equipment ? OT: I think modding here and there does not accomplish as much, the device must be correctly designed from the ground up improve one detail and you face the next bottleneck, Hence the external DAC route :) I have an 3rd party PSU I bought to my SB3 it fits the Touch too , SB3 in Eu came with a really shoddy PSU , I suspected it did not even conformed to standards ? The late logitech SB3 and Touch comes with an much better switcher ( if you can believe that ). -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
