I really appreciate the replies, however based on the responses, I must not be explaining well.
With the YPAO disengaged and in 2-channel mode, it sounds like any quality system with a strong center image and wide deep sound stage.
I have not done it yet, but I suspect if I redo the YPAO and choose single location setup instead of multi location setup, it would be fine. Meaning, in 2 channel mode would sound fine, however I suspect when listening to surround, the people sitting on the edges would no longer be part of the sweet spot.
Here is how Yamaha describes the feature:
YPAO Multipoint Measurement adds the capability of taking measurements at up to eight different locations in your seating area, sending that information to the YPAO processor about the acoustics of these additional locations, not just your prime seating position.
Physics makes it impossible for every location in your room to be calibrated perfectly, but that’s not the goal. In all likelihood, you won’t be watching your favorite movie or TV show (or listening to your favorite recording) while leaning up against a wall somewhere in the room — you’ll probably be sitting in the prime listening location (the “sweet spot”) in front of the TV or receiver and somewhere close to equidistant from the main front speakers. By including additional information in the calibration calculation, Multipoint Measurement makes the sweet spot bigger so that music and movies are more enjoyable for the rest of the family seated in the general area.
