Looking for a Giant Killer Digital cable

No direct experience with their coax but picked up a Oyaide NEO d+ Class A USB for low $ and was very impressed so Oyaide might be an option to explore.  The 102SSC they cite is their replacement for Ohno Continuous Cast Copper, by the way.

Budget ‘Giant Killer’ RCA is an oxymoron.

(1) You only get what you pay for...full stop; . and
(2) The equipment and accessories audio performance in this hobby is a direct result arising that everything is only built to its price-point ;
(3) At that stated price-point strata, the audio performance differentiation between all the perceived contenders and pretenders is negligible to nil.... so its distilled down to "...just pick one of ’em...." exercise.

@blindjim  You have been away for a couple of months. Everything okay?

Chris Somoviggo makes some of the best and best value true 75ohm cables there are -- his current entry level SilverStar is $222 but you could look for one of his products used (although I don't see any of the entry level currently out there)
