Sounds to me mostly like theoretically-based conjecture. Have you listened to bridged configurations to form an opinion this way?Yes, and if you search you’ll find all the info I’ve heard/measured and found on it.
Like I said above , bridging amps makes what could be a good stereo amp, lean towards becoming a mono PA amp. As many parameters take a hit, not just the ones I’ve mentioned above.
Each and every one of us preferred the sound of the bridged configuration, with some describing the sound as now being "more hifi"This statement says it all.
A really good amp should sound big, tight and wash over you with dynamics and detail that don't sound like it's coming from any of the the speakers drivers, and have a sound stage you feel you can get up and walk into.
