That's a good suggestion. I've got one coated plug in each zone of my Denali v2 distributor and I could try coating the other outlets in there. I was just a little concerned about the AC outlet and residue because I rent currently, and was just imaging a family with small children moving in after me. If it was my own place I would do the main AC connected to the Denali and use a couple coated PS Audio Noise Harvesters in other outlets.
It's wild how wide and spacious my system is all of a sudden. Despite all my Shunyata cabling and power filter, fancy fuses, optical isolation etc there must still have been enough noise in my system that was increasing L-R channel crosstalk. It sounds about 2-3 ft wider now.
