I have been surprised recently about the difference in digital cables. I have had a Gotham for a few years and didnt think it was bad but then got a Belden from Gazjam. This was a big step up and convinced me that there were significant differences in cable design and quality.
Today a cable arrived FOC from Mike Homar. Very nice and expensive looking connectors on the end of a white cable. Nearly wrecked my 7520 trying to push them into place before I realised they were locking RCA's
Wow, when I played some music Bob Dylan jumped out of my speakers and shook hands with me. This is a big an upgrade as changing an op-amp to me.

Now perhaps Mr Homar would explain the design of his cables?
