My Yamaha A8A beta tester story continues.
After trying to fix the sound issues the AVR had after all the calibrations, multi point, height, manual, last night I snapped. I did a factory reset of the AVR only to find that it sounds good - not fantastic - with no calibration. It has a sibilance though but I cannot identify the source yet.
YPAO introduced a strong sibilance and voices became fuzzy without clarity. Regardless the DSP or Surround Mixer used, the AVR was muffling the voices in the center channel. Also, all the sounds that came from there were softer that the ones from the other channels despite the fact that using the tone generator I measured the volume of the center channel 2-3 db above all other speakers.
Redid YPAO calibratien only to have the same issues with voices and center as before the reset.
The AVR still have a very wide soundstage, much wider than the V6A but somehow sounds not as clear. I start to wonder if the unit is not faulty.
