I saw this offered up by Proaudiostar the other day and decided not to buy it. It seems like a great price for a boutique amp, but I just couldn't find enough reviews or information online to justify spending $1000. If anyone gets it, it could definitely be a super solid deal if it turns out to be a fantastic amp.
