Couldn't agree more, I have three source components and spend much time with each trying different power cords and interconnects till finding the best combination.
It is rather amazing how much better a component can sound with better matched wires. I admit that I have limited wires to try, and I'm sure there is a combo I don't own that could provide better sound. Never the less what I have has allowed me to fine tune each components sound to a much more enjoyable experience.
