The most detailed speaker cable??

The most accurate and revealing speaker cables I have listened to are the JPS Labs NC2. I wouldn't call them bright, just extremely accurate and detailed.

Give the new e-ticketcables a try. They have a silver/copper hybrid that is great.

Expensive cables sure have cool names.

I recently purchased the Spletz anti-cables out of curiosity to try in my system. My early impressions are that these cables are remarkably clear and detailed. They are not bright but ever so slightly forward. Could be just what your looking for.

My system is fairly similar to yours and I would expect similar, favorable, results in your system. I recommend you try them.
