Is There A Reason for Mono Amps for Ultra-low Noise Class D Modules?

With ultra-low noise Class D modules, like the Purifi Eigentakt, would there still be an audible benefit to having two mono amps, as oppose to two modules in the same case? Or is it really just an aesthetic preference?

Note, I'm not asking about the advantages and disadvantages of Class D versus Class A or A/B.
