I have a PS Audio HCA-2 amp and replaced the dual runs of larger gauge Monster output wiring with quadruple runs of Jena Labs 18 ga. cryo'd wiring with outstanding results (everything better, no downside).
It was such a transformation for this amp that I started thinking about capacitors next. A guy on AA (Fiddler) used Black Gate caps on the four caps in the signal path and I made the same mod last week. Way too soon to tell what the final break-in sound will be like, but it's already doing things better than before (weight, low level information, decay, air etc.). The problem is it's still changing everyday. When you figure I've only added $130 to the cost of this amp with both mods and am now very happy with what I've got, the mods are a real cost-effective upgrade.
