Greetings. I don't believe you'd load Minimserver on your Bryston, but rather on a NAS that stores your music files and also on a network attached computer. I don't know if the Bryston can be used as a DLNA renderer, but if it can, you'll be able to see it on your network and select it via the controller, BubbleUpnp on a phone/tablet.
I don't know if there's a posting restriction, but posing this question to the Bryston circle will likely get your question answered.
