Hi, I am looking for some feedback and advice on the YPAO auto calibration as I found two interesting problems with my new RX-V773.
Speakers setup: 7.1 Channel with surround back speakers.
Testing sound source: 2-channel musical CD, input from HDMI, Optical, Coaxial cable
1. Sound distortion when play back in STRAIGHT mode, only when Parametric EQ is set to FLAT or NATURAL .
2. The sound gap of loudness (same sound source and no change of volume) between STRAIGHT and PURE DIRECT mode is big, could be more than 15dB. STRAIGHT mode is louder.
I use YPAO auto setup, I tried single position, and multi positions (2, 3 and 4 positions). I found the it works fine if calibrated with single YPAO measurement. If taking measurements from more than 1 position, sound distortion appears and sound gap increases. It happened to two sets of RX-V773 which included the replacement.
