I got my Signal Cable speaker cables and IC's yesterday, and after giving them a while to burn in (I'm still not sure about that theory!) I must say that they are really nice! Very nice improvement over the Canare Star-Quad cable I was using. Between the Cambridge Audio Azure 640C and the Signal Cable the SDA 2A's are sounding like a new set of speakers! I don't want to start an argument over which speaker and IC cables are the ultimate best, but you can't argure with the value that Signal Cable provides at their price point.
