Yes, those transformers and capactors are not sufficient to filter out all the AC noise. Different metal and metal structure used in the power cords and various components have different noise conduction characteristics. Some conduct noise better than the other. Ever experiment with different power cords and found some sounded brighter, or some with lacking clarity, or some with wider sound stage? This is due to different noise conduction characteristic in the cables. Once noise is removed/suppressed, many power cords will sound similar. Likewise for interconnects and even DACs. For instance, the Benchmark DAC1 will sound almost identical to the TP's AKM 4396 DAC, once PPP is in placed. Otherwise, you may hear Benchmark being inferior to the TP's DAC, all because TP has a better power supply than the Benchmark. This is because TP's super regulators helped reduce noise better than those 7805/7818/7918 regulators in the Benchmark. -- Kuro ------------------------------------------------------------------------ Kuro's Profile: http://forums.slimdevices.com/member.php?userid=16701 View this thread: http://forums.slimdevices.com/showthread.php?t=52348 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
