(Eternal caveat: I've never used the Denon AVP Control plugin, having
written my own back when I used direct RS232 control.)

Max volume: my plugin asks about a max Denon volume in dB. My
expectation is that you'd set that to match the volume limit set on the
amp. I forget where it is in the Denon setup screens, but you can set
the max volume to one of a few specific values, ranging from -20 dB to
+18 dB. The minimum volume is -81 dB.

When you change the Squeezebox volume, my plugin calculates the nearest
half-decibel (or, for secondary zones, full decibel since half decibels
AFAICT are not availble except in the main zone). Set the SB volume to
"27" with my plugin thinking +18 is the max volume and plugin calculates
the amp volume should be (-81 + ((27/100)*(81 +18))) = -54 dB. If my
plugin thought the amp max volume was 0 dB, then SB 27 would be Denon
-59 dB. You might be able to do something like what you suggest by
configuring the amplifier to allow +18 but telling my plugin its max
volume is 0 dB, so that LMS would never set the Denon above 0 dB but you
could turn the amp knob or use a Denon remote to go louder. But there
are some conditions under which my plugin will resync the volume (for
instance, if set to poll the amplifier, when it sees the amp power
status change from off to on, it will set the amp volume to match the
Squeezebox [because any volume commands attempted while the amp was off
would have been rejected**), and if you had manually increased the amp
volume above 0 dB, my plugin would decrease the amp volume back to 0 dB
in those scenarios. Also decreasing the Squeezebox volume by even 1 of
the 100 steps when the amp was set signficantly higher than 0 dB would
lead to a significant drop in the Denon volume. So I would not recommend
that. Also my plugin refuses to control an AVR unless the Squeezebox
audio output is fixed at 100%.

On my setup, I have a modfied version of Michael Herger's MusicInfoScr
set to display volume on my SB3 in terms of Denon dBs instead of SB
0-100. My whole family is now quite comfortable thinking in decibels.
;-) That will only work right if my plugin knows the actual amp max
volume, as it translates the fictional Squeezebox volume into what it
thinks the amp volume should be; if the amp allows volume +18 dB but my
plugin thinks it maxes out at 0 dB, then it would show 0 dB on the SB
screen for everything from 0 dB to +18 dB.

** FWIW Yamaha's YNCA TCP protocol also rejects things like volume
changes when the AVR is in standby.
