Doug,

One of the beta testers, JeffLH, posted the 950's menu screens. Here is the Input Configuration menu:

Input Config

Source: DVD
Input: Coaxial 1
Mode: PL2 Music
Treble: 0dB (+/- 6dB, by 2dB increments)
Bass: 0dB
Night: No Comp (DR Comp 1 to 4)

Return to Main Menu

As you can see, there are some parameters that can be set on a per input basis. While they're not the same as the speaker level settings that you were inquiring about, the Bass & Treble adjustments should help you somewhat tailor the sound of each input to your liking.

And yes, there are pre/pros and receivers that let you adjust and store more parameters, including speaker levels, for each input. But I don't know if any of them are at this price point.
