I'm using the HDXV cable also between my Sony S7700 and Nixon Tubedac. Prior to that I tried, Harmonic Tech cyberlink copper, Nixons own digitalcable, Kimber D-60, Bolder nitro (non-bybee), Cardas Ultra fast and Audio Magic Sceptor. Prior to the HDVX the cable that had bested them all was an Audience AU24 digital. The HDXV was noticable better than even the audience in terms of clarity, lack of fatigue, palpability and detail. There was/is nothing over emphasized, things just sound real. It's an excellent cable made even better by the price.
