Yep. Have two of 'em for my 300B monoblocks. Love 'em to death...MUCH better than stock. Haven't tried any other cords but my Dad tried 'em against his Black Mamba and said that while the Black Mamba was better, it wasn't by much. Now that your into DIY, you need to build some Risch Twisted Pair IC's. They'll blow your mind for 50 bucks. Cheers!
