^Yes. [edit to add: I am responding to GetGray]
Chris and I discussed this and through
my slow motion video analysis discovered that the annoyingly fast volume changing speed
only occurs at levels
lower than -8 or -10.
So if you can keep your use higher than this, the volume ramping speed is nice and smooth/slow.
Ah, but what if such volumes are higher than you actually like using? The answer is to calibrate through the auto mic/Audyssey setup and then uniformly reduce the gain of
all of the channels (including sub) of your power amps, or, conversely, decrease the efficiency of all of the speakers (including sub), until use of the product in the range it works most smoothly at is also acceptable in terms of SPL to the ear.
This should be a snap for people with power amps that have gain controls (volume), ideally with visible, calibrated divisions (you know, like "11"

) but people without would need outboard potentiometers and possibly an SPL meter to ensure consistency between channels (if they are separate and all channels are not "ganged together" on one master knob).
One could possibly re-purpose an old AVR with a multichannel in and preouts to serve this function. It, effectively, becomes the "multi channel outboard potentiometer".
Note: Use of "dynamic volume" and "dynamic EQ" may not function as expected if recalibrating as I've just discussed. [I don't use either.]
