wouldn't you also likely have less EMF/AC noise interferance with separate mono units?
"Less likely"? Good question, made me think.
What you're really asking is: "Aren't monoblocks inherently better because there would be less EMF/AC noise interference between the channels"?
Originally, the Mark III's were manufactured as monoblocks not for reasons of noise suppression, but to make them affordable. In the Sixty's (of which I am a product), a whole generation of excellent and highly successful amps combined two channels onto one chassis. The good ones, I'm sure, were quieter than the Dynacos.
I have a Harman-Kardon Citation II which is dead-quiet. Amazing, considering the circuitry crammed into the chassis! My point is, it can be done but the challenge (and fun) is to do it properly.
With attention to detail including the use of a power toroid, transformer orientation, more generous spacing between components, shielding and build quality, a pair of Mark III's on a single chassis will be quiet. Just imagine two monoblocks sitting next to each other.
