Just wanted to comment on the necessity of having ICE amps (the Wyred ST-500 in particular) powered continuously:
I ran the ST-500 for a couple of weeks directly from the wall using both the Sunny Cables and later, the Windigo (about a week each) continuously VS using the PS Audio P-600 and turning off the amp daily. NO CONTEST---I consider the P-600 essential. It brings a level of detail and focus that, even cold, sounds better than the ST-500 into the wall direct left on continuously for 1 week. I certainly hear an improvement when the amp has been powered up for a few hours but, I can't say I would be willing to eat the increased electric bill generated by leaving the PS-Audio power plant on all the time. Interesting experiment--thanks for the advice.
