I recently received a pair of M700's to drive my Martin Logan Motion 60's and was impressed with them right out of the box and that hasn't changed in the ten days that I've had them.
I was waiting for new Cullen Crossover Power Cords to arrive before really putting some hours on them which I was finally able to do this weekend and I think Ill be keeping these amps. I was bi-amping my ML's with a NuPrime MCH-K38 so I am using both sets of speaker outputs on the M700s for an easy transition.
These amps run cool so Im not concerned with having them stacked even while leaving on 24/7.
My one complaint if you can call it that is the blue lights on the front power button of each M700 are rather bright and I dont think they can be turned off so Ill prob end up putting some tape over them.
