That's right but you know after all the tweaking, I found that I only need to use the following:
1. Stereo: calibrated levels.
2. PLIIx for music: for some pieces (jazz and classical), lower the volume on the fronts by 5dB to deepen the sound-stage. For all other pieces, use calibrated levels. For some other pieces, go to a phantom centre.
3. PLIIx for TV/cable: calibrated levels
4. PLIIx for movies: calibrated levels but sometimes boost the center as required. A couple of times I used a phantom center.
5. Dolby and DTS for music and movies: calibrated levels with some minor and movie-dependent adjustment on the centre.
