I recently got a muso, very pleased with it, connectivy is good it just works spotify, optical, air play, Bluetooth etc..
Sound quality is subjective but I am often left wondering how does it sound so damn good, very pleased with it.
I would say the demo I heard in richer sounds wasn’t as flaterring as it could be should really have asked to set it up in the demo room not shop floor as it certainly Sounded even better once set up at home as that’s were its more suited of course.
Sportify Premium is/was 0.99p for three months and the better quality streams really suit the naim, there’s also some high quality Internet radio streams that are pretty good too.
App works well on iOS phone and iPad, not tried android,
Only criticism might be the remote it could be a little weightier and of a better material but really that’s as picky as I can get with it everything else is spot on.
