Not quite sure we're using the right terminology here.
The MC200 is the storage unit, media server AND end-point.

To get music from a Sooloos system, you need all three. As the OP has an 818, that's his end point.

So for the OP, the MC200 is acting as storage and server, both of which are needed.

A few options:

- Use just the MC200, as a server and storage, which isn't cheap for it's storage level. Having said that, I've previously own one and found it VERY reliable and user friendly.

- Use the MC200 as a server and host some/all of your music on a NAS connected to the MC200. I got the impression that Sooloos will accept a variety of NAS, as for storage, there isn't much in the way of hardware requirements.

- Use one of the newer/better NAS. I believe that some of the QNAP units might be able to act as both storage and server (please correct me if I'm wrong on that).

- Switch from Sooloos to Roon, which would need it's own dedicated server (typically a PC or Mac). Roon can be hosted on one of the more powerful NAS (think it needs an Intel i5 chip or similar).

Personally I'd suggest you look at Roon for your software, it is more user friendly than Sooloos.
