That's interesting. I've just compared the test tones from the 990, with the Avia test tones through the Oppo (using SPL meter). The mains are the same level, but the center and surrounds are 4 to 6 dB louder with the Oppo/Avia disk. I'm guessing this is because I left the speaker setup as large for center and surrounds on the Oppo. Will adjust tomorrow and re-check, but this might also be useful info for others as well...
