Kalili.....I forgot to mention, I had built a dedicated circuit into the audio room to a 4 outlet high grade furutech (dark grey, don't know which model). So no interference from appliances. However, the shunyata power conditioner is plugged into it. I have everything plugged in for the "conditioning" of the shunyata and the surge protection. I am a bit concerned about plugging a $35,000 system directly into a wall jack bare bones with no backup protection. Then again, I don't want degraded sound quality either, which is why instead of say...an apc style surge protector...i opted for a much more expensive power conditioner that is advertised as an audio grade conditioner.
But I should plug the power amp in directly is what I am reading....but the preamp is not necessary to plug in directly? I will do that, since it sounds like like the power amp has special considerations.
N80....you could try a surgex surge protector. No degrading from surges in the surgex products from their proprietary technology. Also, if not that, you could purchase a multi outlet power cord electrical box where you can plug/unplug your components without worrying about wearing out your wall outlets. I am having one built right now by JT Dynamic Power. Jason has built all of my power cords and interconnects....fantastic stuff at very reasonable prices. Great guy too
