Best Copper IC under 200.

I would suggest the Tara Labs RSC Reference Generation 2 although that may top the $200 a bit, like $215-220 I think. Or if you want to stay strictly under $200, then the AudioQuest Viper at $195 (1M). Both of those are close in performance - neutral, revealing, good tight bass on the low end. I auditioned both recently and went with the Tara Labs. If you go used, then you can maybe even find the next step up for both, the Tara Labs Master Gen 2 I have seen used for $195, or the AudioQuest Python should be in the $200 range used.

I completely agree, having recently used both TARA Master g2 and Viper. Also, AQ Opal is discontinued, but is a brilliant cable (replaced by viper) and should be cheap.

Kadlec, my thoughts are try MIT through Audio Advisor - 30 day money back guarantee. 330+ or even term series, the term 2 ic is around $80, I know MIT speaker cables and Thiel are an excellent match, I've got em. Not sure about Cary/MIT though. I had Tara Ref. Gen II and did not like in my system, CJ pre and Classe amp.

An all copper cable worth considering is the Harmonic Technology Truth Link. Recently I had to the chance to compare them (in someone elses' system) against a couple of Nordost ICs and left with a very favorable impression. The Truth Links are usually available used for ~$125 here on Audiogon.

Unfortunately, I am only familiar with your pre and speakers, not the amp and source (which I hear good things about). Given that limited knowledge, I'd say the Truth Links are worth a listen.

I second the truthlink at $125ish used, $250 new. I a/b compared it to a nordost spm. It lost on sheer resolution, but it wasn't by much. Another very good cable I tried is the Audioquest quartz x3. I think you can find those in the hundred dollar range used. It's a very good idea to try a couple of cables with your system. Their performance is system dependent.
