Someone asked did I try yet. Yes I have tried it under amp and it seems like I've got a little better bass response. I think it has helped, it definitely hasn't hurt. Getting harder to tell on some of the tweaks as it's sounding so darn good !! Clarus power cables have really helped. Don't let anyone tell you power cables, interconnects or speaker cables other than stock do not make a huge improvement because I've tried several and from very good manufacturers. Regular wire or stock power cords are costing you big difference in sound, definition, tonality, soundstage and resolution. Good cables from highly regarded , respectable companies make an enormous difference and especially once you go up the ladder in equipment performance.
