I'm not buying your math here. If that were the case, then it would be literally impossible to detect any differences between various PSUs. The thing is that when an electrical audio component operates, it tends to interject certain random noise back into the electrical circuit. If your audio chain is not properly balanced, these tiny electrical noises can feed back and get magnified along the audio chain and then emerge at the other end (i.e. in your speakers) as interference. We've all heard that (the unwanted buzz and the hum), and we've all heard how great the music sounds once we manage to clear up that congestion, if even for a bit. When we upgrade an audio component and go with a higher quality one, the benefits are mostly in the area of noise reduction. It takes careful engineering and a lot of know-how to be able to tame those pesky little interferences, which explains why is this hobby so bloody expensive. ------------------------------------------------------------------------ magiccarpetride's Profile: http://forums.slimdevices.com/member.php?userid=37863 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
