VRS Revelation - any experience?

I'm trying to decide on a hard drive front end for my system. Spoke with Vincent at VRS Audio Systems. He says he now has just one model, the Revelation. It uses its own proprietary soundcard putting out AES/EBU, and uses its own proprietary ripping software, according to him. It has 600 gig HD, and 600 gig backup.He says no other system holds a candle. It retails between $10-15,000.
Does anyone have firsthand experience with this product, and is it superior to all other HD-based front ends?
