www.pbnaudio.com. I'm friends with Kevin, the owner of The Sound Station in Bartlesville, OK (
www.thesoundstation.com). They are dealers. The system I listened to is the one on the home page.
The system, at the time, was using a pair of the Olympia-mini amplifiers $8,500/each. They now make a $20,000 amplifier, but I haven't heard that.
It had a top-of-the line DCS digital front end, Passlabs preamp and Montana KAS speakers. Nordost cables all around.
This amp (system, for that matter) is the most grain-free, invisible system I have experienced. You know how a less ambitious amp seems to be pushing the music out, instead of "breathing" it? This one breathed it better than any other amp I have listened to. TOTALLY grain free. Amazing.
