Are those the Aural Thrills tube amps? Never heard them, but he makes pretty nice IC cables. I have a pair of Air silver XLR's, a pair of silver RCA IC's, and a pair of copper IC's. All are very good. Not as good as MIT Shotgun S3's, but the Aural Thrill are 1/4 the price too and are about 85% of the MIT's. Great price to sound ratio!
