For both cost effective and excellent results, I just bought 2 of those Edge 10' power cords for $75 each on auction and stuck on my Spectral 360 mono blocks and wow! Was very impressed and happy hearing the results. From stock cords right off the bat,you hear an increased sound stage and imaging in the mids. Very quiet power cords and I notice an increase of detail in the upper mids and tighter bass. I am going back and getting a few more, for my Sprectral DMC-20 preamp and Spectral DAC. I have a pr. of Thiel 7.2s'. I also have older Levinson Amps (20s) and had excllent results. -Brent
