I use a pair of Triode Wire labs "American 8s" that I picked up used in the trading post here. I like the ease of running the TWL wire and I do think that they help the bass response (I get the impression of an additional "tightness" and slightly more extension) vs. the stock PCs. I've seen some good deals on TWL cables on AC. Worth looking out for. I also run Dave's PC to a MiniBuss and a 8+ to my tube amp. I'm slowly upgrading all my PCs to TWLs.
