Personally I am more interested in the feature set of the possible Integra 80.3 (or Onkyo equivalent).
Then have a look at the Onkyo TX-NR5009, 'cause the Integra DTR-80.3 receiver will just be a clone of that (just as the 80.2 was a clone of the TX-NR5008) and the DHC-80.3 pre-amp will be a clone of the Onkyo PR-SC5509, which is just the TX-NR5009 minus the internal amps and plus XLR connectors
Having a quick look through, I'm rather surprised to see two expected features "missing":
1) No Audyssey LFC - I was really expecting to see this.
2) No 11.2 pre-outs. The Denon 4311 had it, I'm expecting the Denon 4312 to have it. I can understand having 9 channel amps, not 11, but what would it really cost/take to put in the extra pre-outs? Even if you could only run 9.2 signals, it'd be nice to be able to connect an 11.2 speaker configuration and then choose which 9 speakers to run (although being able to run all 11 would, of course, be even better
)
