I'm using the 2700 as an audio only prepro, Rotel 1095's for amps.
I started off with an analog RCA connection (Audioquest Diamondbacks) between a Denon 3910 and the 2700. After one movie DVD and one music
CD:
In 'direct' mode, not quite as musical as my AVM30. Frequency response a little overemphasized in the 2k-4k range, a little underemphasized in the 200-400 range. On ....Saint-Georges Violin Concertos V2, Naxos 8.557322, violins were a slightly steely, lower end of body resonances was not loud enough. Still the Yamaha is good enough to present good imaging and 'hearing into the performance'.
With front presence speakers connected, Stargate Season 1 disc one in DPL II had the same frequency response compared to an AVM 30 as above -- even so, the Yamaha beat the AVM30 in theatrical sound field. I have yet to hear a front end that can beat, for subjective enjoyment, Yamahas theater sound fields.
The sound field programs are not the same as the 2500/4600/2600. Yamaha's 'Enhanced' Dolby decoding modes are no longer menu options. Also, DPLIIxMovie mode now requires rear speakers -- I'm pretty sure I was able to run DPLIIx on the 2500/4600/2600 in my 5.1 setup.
Gene will have some interesting comparisons to make
