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.
I just got their speaker cables and they wer awesom...very clean. I replaced my Monster M series with these. I have used their cables(GA-0) and they were so good that I am converting most of my connections to GA-0's. Very clean and detailed sound.
I have been using the GA-0's myself for a few days and they are very good. I have not tried many cables so I was looking for someone who could corroborate my findings. The speaker cables may be an interesting next purchase. Bob
