The Nasties are gone. I had the thought , but Viggen cemented it in my head. I moved all the power cords away from the interconnects, and the detail has returned ! If you think about it, most equipment has the PC inlet on the left, so if your installing dedicated lines , have those off to the left so you do not run your PC.s crossing your interonnects. Im still going to try some of the tweaks though, some sound very interesting, Thanks to all !
