I've been using his Pulsar ICs for over a month now. Although I only have about 75 hours on them, from the start I couldn't believe the clarity of these wires. Like most of us, I did the IC & speaker cable carousel using brands like Audience and Acoustic Zen. I then tried several "low cost/high performance" cables seen advertised and talked about on Agon with a 30 day return plan. The instant I hooked up the Pulsars, I knew it was what I wanted. Although the other cables I tried were good, I couldn't distinguish between them very much. I'd pull my wife in for a sanity check while I jumped around behind the equipment swapping wires. The first 5 seconds of the first track with the Pulsars, we both knew the clarity was clearly better than any of the others. I'm also using his star-quad bulk wire for speaker cables. Additionally to the product, Chris is a pleasure to do business with.
