I have a buddy who is way high end and he recently got 2 sets (biwire) of the speaker cable and a run of the balanced interconnect. He actually called me at work on my cell phone to sing the praises of these cables. He says that it is a whole lot better than both Transparent Ref XL and Nordost SPM. I'm sure he would be more than happy to expand on his praises if you want to email him. His name is Tony and his email is Akob007@aol.com. I can't wait to try it myself, it's just a little to pricey for me right now though.
