Power Cord Wall to Conditioner

A quality PC usually comes already equipped with its own good quality power cord

Otherwise get something decent - even DIY with quality cable and connectors - at the sub $150 price range.
The PC is another intervening filter in substance so no need to go overboard.

What are you using on the components themselves? Synergy with these would be nice.

With the system that you have, for God's sake, get a good power cord. If you don't want to buy new, I think that I know where you can get Silent Source The Music Reference for $1,000.00.

Check out offerings from Cullen Cables and Signal Cables. They're approach is straightforward and voodoo free and won't break the bank.

Anticables make some extremely good power cables that perform very well.

I'm in a similar situation and am pleased with Cullen cables.
