Behringer watts ????

here again, all this perceived louder deal is a reflection of the disparity in the measuring or comparison methods.

to be fair, there would have to be something regarding the musical vs ugly distortion components of tube vs ss

and IF everything were dialled up equivalently with only spl meters as a judge of loudness, your audio pal is correct
doesnt matter what black box drives X amps at Y volts into speaker Z.
