I recently upgraded to a Aurender N150, I'd go with them, thing is built beautifully, and sound is phenomenal, dead quiet and I put 500 CDs on the internal SSD in .wav and they sound better than ever.
I used to have a Sonos Connect mod wright and all my music playing from a NAS through the modded Sonos and it sounded awesome, the Aurender playing them directly from the internal SSD blows the old setup away, I do also do a little streaming on Qobuz, but the internal SSD files sound the best, the HiRes stuff on Qobuz is pretty good though.
My vote is Aurender, the only thing I wish they did was include a IR remote, just for play/pause and skip tracks, I dont love having to do everything while getting a tan from a ipad screen during a listening session.
