Speaker cable help

Hello skipper320,

Of the five speaker cables that you mention in your post, I have auditioned four of them in three different systems.  I'm very lucky since I do professionally reviewing I get to hear a lot of gear on a on-going basis.

A speaker cable that costs less or about the same that out performs four of what you were interested in is Black Cat Cable's Coppertone which retails for $300 for a ten foot run.  It a terrific performer and so far has worked in every system I have tried it in.

It'd be most helpful to know what cables you're using now and what kind of improvements you're looking for. 

The Black Cat Coppertone is excellent,clear and detailed with a touch of sweetness.Kimber is detailed but leans toward cool as opposed to organic.Analysis Plus oval 9 is organic and natural sounding and slightly rounds off transients,a perfect compliment to an overly detailed system.Of course YMMV but these are my impressions.

Wywires should sound excellent with your speakers and amp. This is my guess not knowledge, I heard your speakers but not the Plinius. I just tried Wywires Silver and Platinum interconnects, the former is excellent cable and the latter is great cable.
Alex of Wywires has 30 days return policy, if I remember right.
They are accurate balanced cables, nothing is harsh or too warm or cold. Excellent dynamics and correct harmonic presentation.

By the way, in my system WyWires Platinum mixes with Tchernov and Purist Audio interconnects. Speaker cables are Purist. I first got the Silver and almost immediately upgraded to Platinum, got them both used.
