I did not want to put this in Early's thread and decided to start a new one.
For those that want to hear a quality PC for what would probably cost you about 10 bucks to audition....I highly recommend these. These are built by my dealer who is just awesome to deal with and he will let you audition them for 30 days with a money back guarantee. The only thing that it will cost you is to ship them back. They worked very well on my tube amps. For the amount of work that goes into them, they are a total steal.
I found them to work a lot better than my PS Audio Statement
I have also auditioned the Black Sand Silver MKV (a highly regarded PC) and these sound a lot bigger.
With these cables my soundstage got bigger (probably due to increasing dynamics), greater separation of individual instruments, a blacker background, less upper frequency edge, and an overall warmer, more accurate sound.
