Power cable thoughts for Krell Kav/Proceed Amp 2?

So I got a ton of help asking about ICs last time, so I am down to PCs. Lots of people suggest getting power first, but great power cables and zero ICs doesn't work well either... What brand and model cables have you found to work best with Krell KAV 22/3250 series and a Proceed Amp2. I'm using one of each in a 7.1 setup. I've read Acrulink, Kimber, Cardas and Nordost seem to be the most popular. I just want the clearest sound I can afford. Also have a HTS 7.1 and a DVD std and a Denon 3930 that all need cables. I have one Cardas Quadlink that I'm unsure where to use it and what else to buy. Thanks as always for any help.
