Gonk,

I contacted OPPO on this issue. Just wanted to share their response.

I think this is an important issue for 7.1 ananlog output to receivers that don't have on board processing of the new HD formats.

Joel,

There are inherent differences between a raw audio signal and a PCM (pre-processed audio signal) in terms of volume output levels and expected bass management.

When you are working with the DV-981HD and comparing the difference in bass performance between digital coaxial (bit stream) and multi-channel analog (PCM) are you using a SPL meter to ensure that your output volumes are the same?

The DV-981HD and the DV-980H have been called "bass shy" when the player is doing the audio decoding. The BDP-83 should not have similar complaints, but you may want to wait for third party confirmation.

Best Regards,
