I have had some decent gear for many years that came with quality ICs and Speaker cable (Synergistic Research) but have been using the same PCs that came with everything. Of course, I know there are 2 camps when it comes to this discussion so I am un-interested in hearing that wire is wire and the thinnest wire they supply you with new gear is good enough. I have been reading reviews and observations on PCs for years and decided that with free shipping to me, and a 30 day return policy, it will be cheap enough to test this all out and return them if they do nothing to improve my current sound. Last week, I rearranged some of my gear so the main 2ch system was all together and also made sure all the PCs and ICs were routed as good as I could get them. I also noticed that all the PCs I have are 16 gauge, except for the PC for my APC unit, which is 12 gauge. I ordered 2 Pangea 14SE MKII cables for my Pre and CDP and a PS Audio PerfectWave AC 3 for my Amp. (I was a little worried about the diameter and stiffness of the Pangea AC9 so opted to try the PS Audio instead.) I just ordered them on Saturday so waiting their arrival so I can get them in place and see if they help or not. I have also read that running your gear thru a Power Conditioner or Surge Suppression may negate any real or perceived improvements if the cable from that unit is not also upgraded. I can play with that by swapping the stock cable with the PS Audio cable as a test. I will update this thread with my observations as soon as they arrive and get swapped into my setup.
