I just purchased a pair of the Carver 305 KT-120 tube monoblocks are so far I am extremely impressed with them. A friend brought over his new Triode Wire Labs American 7 power cords and we replaced the Pangea's that I had been using; astonishing improvement! I am purchasing two for the 305's. Bass was immediately noticeably better, more dynamic and extended, midrange and top end clarity was improved as was soundstage width and depth. Everything sounded bigger, more refined, and just most muscial. Here is the link:
