I just fired up a clean 20 amp circuit with 10 GA wiring, an audiophile grade recepticle (PS audio Power Port, a PS Audio 10 Ga power cable to my Plinius 9100 integrated. The improvement in sound for my system is absolutely great. My Totem Hawks have far more weight, clarity and impact. However, when not spinning a record, there seems to be a low level "hash" that is accentuated when I turn up the volume on the amp. It does not seem to be audible when listening to my vinyl source, but it was not there prior to hooking up to the outlet that is directly connectd to the 200 amp house panel board. Any thoughts?
