Ah OK, I double checked the input sensitivity vs power output into 8 Ohms on each of his two amps. They do in fact calculate out to approximately the same GAIN of 30dB. 1/3dB difference actually. Not much.Amp #1:
100-Watts into 8 Ohms =
3.536 Amperes and 28.28 Volts
900mV drive for full output
= 29.95dB GAINAmp #2:
300-Watts into 8 Ohms =
6.124 Amperes and 48.99 Volts
1500mV drive for full output
= 30.28dB GAIN

If you have two different amps with different gains would volume changes become a problem as well???
I believe the volume changes will be proportional.
