The pc is well built but it is rather unassuming looking. If you are looking for a huge, impressive looking, Oh my God there is a snake biting you amp! No, thats just a powercord pc this is not it. The cord is very flexible and user friendly though.
I plugged it in on my Plinius to burn in as recommend by Mr. Kline. I agree with the other peoples finding that pc sounds better new then any other that I have used but the bass was a little vague. After about 250hrs the pc really shined, bass was now tight and extended with great definition. The pc is very smooth and extended in the treble with a great amount of micro detail but lacking any stridency whatsoever. The midrange is fleshed out very nicely and the soundstage gained depth and width and a remarkable increase in dimensionality. I also found it to be perhaps the most neutral pc that I have used which have included Synergistic, Shunyata, VD, VH audio. Unlike others experience it seemed perfectly adequate on my amp and was equally impressive on my pre and cdp. BTW the pc is being used with Oyaide R1s which I guess is what Mr. Kline used when designing it.
I agree that this cord is a very good deal at the $599 price and at its $399 price it is a steal.
