Damn, Matty, I was hoping nobody would think of Luminous since I have a "wanted" posting for a 1.5 to 2 M balanced pair of IC's. I have one pair and they sound great in my system, so I am looking for a second pair to replace my Golden Reference (which are also good, just different sounding). BTW, Bob Crump has posted the signatures are the best copper IC he has heard. Do you know the difference between the Signature and Reference balanced? I know the reference has upgraded RCA's but I am not sure of the difference in the balanced cables.
