I ordered one from usedwire.com with the understanding it was an old Diamondback. I have had it in my system for about a week now running from a PS Audio Ultimate outlet to a Juice Bar. It was an improvement over the standard black cord that I had before. It was a little bright and harsh sounding at first but it as mellowed out and has continued to get better sounding throughout the week. I don't have an actual Diamondback to compair it to but I don't think I got ripped off. Just a little mislead.
