Couple comments, personal and off the cuff. I have not heard this unit.
It's a very expensive receiver (of course no tuner, but it's all in one). Priced @$22k, I'd much rather have the components separated out a bit more, at least between source/DAC and preamp/amp. To be stuck with something so expensive when the source sections get outdated would be a bummer.
That said, I see it used at TMR for a mere $15k. Perhaps the right price for some; for me, I'd prefer to assemble a nice sounding but more flexible system.
