Streamer recommendation

Hi all. 
 

Looking for a streamer recommendation. I love my primary system. Have an Aurender W20 with their additional master clock feeding into my D’Agostino Momentum HD and M400 amps to drive my Wilson Benesch Resolutions with REL 32’s. Have that for my primary space. 
 

Had a great opportunity to build a secondary system in a huge room that is our living room, family room, and kitchen for listening while entertaining or even just casually during the day. I have a pair of Focal Diablo Utopias (and a B&w DB1-D for a sub) fed by a Gryphon Diablo with their integrated DAC. Also using the theater pass through to run a 7.1 home theater using a Marantz Cinema 30. I have very limited space to keep the wife happy. It’s an open room so do t want a bunch of stuff cluttering her area. 

The Gryphon is tucked away in a AV console with the center channel and the Marantz and Ethernet switch are in a pantry closet.  Would like to have a decent streamer. Love the aurender conductor app. Would like some build in storage space to keep the music files built in. Would a Bluesound Vault be enough?  Should I just bite the bullet and get another aurender like an N200?  Or are there some more reasonably sized ones you like?

Your input is greatly appreciated!
