Recommendation for an audiophile speaker cord that is not "bright"?

I will second the suggestion for Cardas.  If you can find a used pair of Cardas Golden Reference, they are excellent and not bright.   Expensive at the time, but can get a better deal, now.  

So........you are demoing some $2000-4000 per meter pieces of wire and you want other peoples advice what is better? OK, I will be like the rest. Why are you bottom feeding with the cheap stuff? Spend more (like I did) and it will sound much better.

Being more serious............It is all about synergy. At the prices you are contemplating there is a better than 50% chance you could find something better for your system at much lest than half the cost (maybe even 1/10th). What cables have you tried so far that sounded OK on your system? How much did they cost? And what are you hoping to improve by upgrading?

@ruraltraumasurgeon Thank you for doing what you do!

I have yet to see one that was bright. Most of them are black!
