Very interested to hear about some hands on experience with the MS200.
I'll let you know when mine arrives.
It does present some interesting alternatives. Now the MD600 runs as a core, I'll be able to sell my RM TwinStore and MC200, replace with MD600 and MS200s. I then have my core and storage in one place, which must be preferable from a stability of network perspective, and located in a rack in the cellar which is good to reduce the noise in my listening room. It remains to be seen what the impact is sonically using the MS200 versus the MC200.
