It would be nice, if someone did a blind a/b testing with these amps Vs a $2000 per channel audiophile amp.
I did that, many years ago..
To compare Crown $400 amp vs my Bryston amps - either 4bst or 7bst I forgot..
My installer gave me a switch which switched the speakers from one amp to the other (both amps were ON and were running the same CD source).
I could identify the Brystons as being some what superior but the superiority was very minimal. Now those were not very high end speakers.. Maybe $2000/pair..
I for one, am convinced that Pro amps like Crown and QSC are excellent for home theatre and are much better bang for the buck. You can spend the money you save on amps, with a higher end audio processor.
I designed two systems for two friends. Both of which, I chose Anthem Processor and QSC amps. I find that such a system is far superior to a $5000 audio receiver, with built in amps. While fidelity of an audiophile amp inside a receiver might well be superior, the "head room" of a high power amp more than compensates.. The high power does not mean that we actually would need/use that power - it just gives better "control" of the speaker cones, with the higher voltage/current available for speaker voice cone extrusion and control... that's my 2 cents worth of belief anyway and I would admit that I am no expert on this subject!
I don't know how good Behringer amps are.. Are the as good as the "typical" Crown/QSC (both of which, I would say, are pretty good and equally good).
Of course, there is no reason most of us typical home theatre users, to need 12kw of power.. As someone else wrote.. perhaps they are suitable for driving very large subwoofers..
