Well you got most of the settings fine....Keep Dynamic Volume on Low.
Source if low then please go ahead and increase the same to 10 or even 12.
In terms of Audyssey setup, levels are done conservatively and hence you can try to increase each speaker by +1db and try.....
If possible, run audyssey again, you may need to possibly do this even at 12 midnight or 1am to get it right.
I use a Marantz SR6010 and after audyssey settings, I changed the option of MultiEq from "REFERENCE" to FLAT and it really brings out the best frequencies in the speakers I use and even output. Based on the specs of my speakers, I have carefully tweaked source levels and even increased speaker levels for all by 2db after audyssey setup. I have retained these settings and added the same for every upgrade I have done for AVRs.
All the best!
