Great Copper Cables?

I would suggest Acoustic Zen either Satori or Hologram speaker cables and their Reference MkII ICs. Matrix would be warmer, but Silver ref has better resolution without being bright and without loss of bass. Between the source and pre the one to use is Silver ref and Matrix ref would go between the pre and amp.

Coincident is an excellent all copper wire. I run them as interconnect and speaker wire with my Atma-Sphere OTL amps and Aesthetix gear. They are very neutral and well balanced. It's probably important to note that I have Coincident speakers internally wired (stock) with the same. These cables are grossly underrated, very well made, and a Hifi bargain (299.00USD/M). I like them better than the Acoustic Zen Matrix Ref.II, Cardas Neutral Ref, or the Harmonic Technology IC's I've auditioned. Audience au24 is a great recommend. Happy listening!

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.

A friend of mine use transparent wires with enacom speaker tweak to tame thebrightness of his Thiels.
