Is the PS audio M1200 D class amp worth buying or should I stick to A/B class mono amps

Right now I'm leaning towards the Cary SA-500.1 ES for $6,600.00 on sale until the end of the year 500W @8ohms and 1,000W @4ohms class A/B mono amps.

I just picked up the Benchmark LA4 line amplifier that will be controlling the mono amps.

@alucard19 Congrats. That is what I use, and it beat all the other contenders I compared it with.
