Let me echo Charlie's suggestions from March 1st.

* 0.5db level trim increments.
* Per-source level adjustments
* Per source default volume levels (When I switch to DVD, set volume to X)

My old Pioneer Elite receiver had 0.5dB trim increments and you can tell. It was particularly helpful fine tuning the center channel. The "per-source" level adjustments would be great pariculary with stereo/bypass/upsample versus 5.1 modes. Finally, having a source volume would be great given the difference in volume between my cable TV and universal player.

I really hope these items are included in the 990 update.
