Apparently they are not available yet; The starting price is $300, which will drop after three months. What makes this thing cool is the (apparent) 5 band EQ in the digital domain, and the ability to control other components, through it...
I do not believe it is Tripath based, but is supposed to contain JVC's proprietary digital amp based on what they call, "hybrid dual digital feedback," which sounds suspiciously like a sort of modified or "enhanced" Tripath design. I have heard its predecessor, the RX-ES1, which is part of a HTB outfit, and the damn thing sounded just beautiful, even in a noisy store, on the cheeezy silver sliver speakers it comes with. It really sounded so good, I came back the next day with my Joule tube pre, explaining that I could only be interested if I could hear it on some better speakers, etc. Typical warm, liquid, resolving power and speaker control-from-hell, I loved it and intend for it to be my next acquisition. When it comes out? Who knows. Put yourself of J&R's list to be notified.
