Hi DJ, long time no see?

You should try to measure both amps output with the same input signal (1Khz for example), same load, before clipping.
Measure the output voltage and current and let us know what you found. You will need a scope to see when it's clipping.

Default 25W can be louder than 75W...

It depends on gain-setting, and input sensitivity.
And of-course, power-supply.

Another thing: when equal VA trafos, but different voltage, the one with lowest voltage can deliver more Amperes...
