You left out better slew rate in the 'pro' camp of bridging.
In any case those "facts" offer a convenient way to make an all-encompassing statement saying bridged amps only offer more watts while taking a hit in the remaining areas. What has, truly, "always been the same" is that it depends; given a sufficiently "sound" amplifier design (those aren't difficult to come by) and a speaker load that isn't downright problematic or too low-impedance, bridging won't invite stability issues. Indeed: what's the relevance of the stated cons as they apply to actual sonics?
Roughly 3x the power though gives you more headroom, ease and likely a lowering of perceived distortion, and if a better slew rate is anything to go by transient cleanness should see an uptick as well - all of which aren't too far removed from my listening impressions of bridged amp constellations.
Not in the least, still fact with Class-D's today.Sorry, Not in the least, still fact with bridged today.In general Bridged AmpsPros=It's always has been the same.
More watts.
Cons=
Worse damping factor
Higher output impedance (has relevance to damping factor)
Lower stability (especially into low impedance’s)
Current ability is reduced (especially into low impedance’s)
Higher distortion.
