This discussion is very interesting.
My guess is the numbers don't really correspond to any particular
value. The designer probably thought the fairly technical numbers
gave the front panel a feeling of "technicality."
my Yamaha RX-1100 (same brand as Rick's receiver, but about 20 years older) has
a volume knob that goes ∞ 60 50 40 34 and by increasingly small increments "up"
to 0, the maximum volume; i believe the lowest number i've used is 24, which is
about 1/3 of the way "up" from ∞; i interpret these as numbers as dB
attenuation from max (expressed as such they are clear without being negative)
so Yamaha apparently has a tradition of indicating volume in dB; yet i could
see marketing dweebs in the mid-90s or later expressing concern that topping
out at zero would hurt sales and thus a concept of a 0dB reference was
substituted for attenuation from max
or it could be that as with many newer AV receivers, there is a calibration
tool included that can listen to the system and balance it, and if possible set
0dB to the 85dB listening reference as mentioned above; i believe one or both
of these is why the dial goes to +15dB
