I agree. Diamond X3 is a significant upgrade from Lapis X3, and a great cable. I was using Lapis X3, Diamond X2 and Fidelity Research Silver Dragons in my system, and just upgraded (this weekend, in fact), to all Diamond X3 IC's. No comparison whatsoever. In my view, it's as good as Quattrofil in the right system. Gthirteen is, however, wrong on one point. Search for Diamond on Audiogon and you'll see there are several pairs for sale. In fact, two pairs were auctioned this weekend, but did not meet the reserve price. Seems like it's not a popular cable these days
