I've found that Wireworld's Polaris cables (all copper) are excellent for extension and detail without glare. The Audience cables that many have already mentioned are excellent also. And I was amazed at the quality of the Audio Art IC-1 cables for sale here on Audiogon, all copper but excellent sounding and dirt cheap. I've heard very good things about the AZ Wow and the Coincident copper cables, but haven't tried them. The Cardas and Harmonic Tech all-copper cables I used in the past were too slow and dark sounding for my tastes. But then, I'm a silver hybrid kind of guy.
Great Copper Cables?
I have a VTL IT-85 (Mullards) with some Thiels and I get some minor excessive brightness....... I'm using PAD Museaus but one time I hooked up my backup bottom scale Audioquests and I lost some resolution but the tone warmed up nicely............ Any way just wondering who makes some of the best copper cables and which models?
