Hey Gray, Being a fellow sawbones and an audio-something I will help. Just finished the same project. I used 3 runs of silver plated, 10 gage, stranded, heavy shielded copper wire and made 2 lines {The wire only had 2 conductors}. I used 30 amp fuses in the box and a line for digital and analog. Used FIM 880 outlet and short runs of JPS IN WALL stuff just for short runs in the wall and more FIM outlets daisy chained together. I use no line conditioners but decent power cords. It has no surge protection and I do still hear a Pop when the dishwasher of heater kicks in. As far as I can tell the first 2 months were breakin time but the improvement was quite dramatic. My OTL amps had the most to gain but even my home theater setup and TV improved but not as dramaticly as the tube amps and 2 channel music system. The cost of doing it yourself is less than a couple of good power cords. If you need the web site for the wire let me know but by all means this tweak is "slicker that shit". I hope your not a Proctologist. Happy Trails
