Well........... I have heard pretty many. Without knowing your system or sonic priorities it's hard to give a real good recommendation. However, in my 2nd system (which is by no means state of the art: Maggie 1.6's, Classe' amps, Sony 9000ES DVD, etc.) I certainly liked Kimber Monocle XL, Cardas Golden ref, and TG Audio better. I started with all Nordost (Red Dawn and Blue Heaven speaker and IC's) and have since replaced them with Kimber.
In my main system I have Purist. If you can stretch your budget this might be the way to go. OTOH, you might just try the Cable Co. and have them lend you some to try for yourself.
