@havocman:
"...unless it's a hybrid cable that has both the OCC single Crystal silver and copper, silver by itself can be a little bit bright unless your equipment is very neutral sounding".
Agreed... but keep in mind when I first checked out the A. Copper and Silver reference IC's, I had both a warm-sounding integrated (Wells Majestic) and a warm-sounding DAC (Aqua La Voce S II) in the system. In this scenario, I found the A. Copper a bit dull, while the Silver Ref. sounded "just right". .
The Hegel is both more resolving and more neutral than the Wells, which is prompting me to try the A. Copper again.
