Sorry, not that I'm aware of. The 8.4 is an avr that I'm considering. I've kinda given up on pre-pros. The Marantz 10 is the one I'd get, if I was OK with spending 7K on one.... I'm not. I'm also in favor of a good AVR with some application to use as a backup, should my external amps fail (and they do).

So now, I think I'm just going to focus on AVRs.... Denon has one coming out this spring that also looks promising (X6800), but I really like how the Integra has balanced outs for R/L/C and two independent subs. Doesn't look as if the Denon AVR will get balanced outs.
