I have a pair od their i/c and they are very good. As far as comparing them to your current cable I am not familar with them.
I replaced my NBS Omega 0 interconnects with audio metallurgy GA-0 - that's how good they are.
I just bought a couple of their interconnects at auction (GA-0)and am awaiting their delivery. They certainly look interesting and their feedback looked promising. Has anyone heard their speaker cables? Has anyone else heard their other products as well? I noticed that their auctions get quite a bit of activity so others have apparently noticed their products.
