I am seeking massive wpc monoblock amplification for a new stereo system. To this point, three impressive amplifiers have been recommended to me. I have heard one.

McIntosh MC1.2KW
Boulder 2050
Pass Labs X1000

All three have received favorable reviews to different degrees. I would very much enjoy reading thoughts from any of you who own [or have owned at one time] one or more of these three monoblock monster amps.

Equipment paired with the amps?
Musical?

Thanks!
