I have some questions please

1. With 7.1 speaker set up, what kind of signals sent to Rears and Sides for Trifield and DPLII
Both PLIIx and Trifield are ambience extraction algorithms, with PLIIx being far more agressive about the extraction.

2. DPLIIx(7.1) is supposesd to be better than DPLII(5.1), how about for Trifield? is 7.1 set up supposed to be better than 5.1 for Trifield?
PLII and PLIIx are really the same at 5 channels. IIx just allows for 6 (and 7) channel configurations and adjusts its output accordingly.

For Trifield, the surround channel output is very minimal in my experience (as it should be) and as such I don't notice a dramatic difference between 5.1 and 7.1.

3. How's Trifield compared to DPLII/DPLIIx
Trifield's primary function is to solidify the front soundstage with the more sane inclusion of the center channel. The downside is that it pretty much demands an identical CC loudspeaker in my experience. This isn't the end of the world FWIW, but I find that the Trifield experience is dramatically improved with identical front speakers.

4. What % do you listetn to various modes for music (for example, Stereo 50%, Trifield 30%, DPLIIx 20% etc)
Trifield 90%. Stereo 10% for review purposes only. PLII/IIx don't cut it in comparison for music listening anymore.

5 What are your speakers and the bass management setup for the multi-channel music such as Trifield and DPLII
The same as for everything else. Crossover at 55Hz for all speakers for all material.

I have JM Lab Electra 926, CC900, SR900, REL Strata II. Right now, I set no sub for Trifield and have my REL connected to high level to take care of anythin below 38hz, and for DPLII I set the processor to send below 55hz to sub.

It sounds little boomy for DPLII.
I prefer keeping the system identical at all times, but that's a matter of preference and how do you argue about that?
