Do you like MusicCast? Does the amp section sound good with your speakers?
If it solves your problems and sounds good then I wouldn’t bother replacing it just for the sake of having separate boxes.
If you think there’s room for improvement in performance then sure, but even then, maybe you don’t need to replace the whole thing, just add separate components like a better streamer or power amp section or whatever it is you’re not happy with.
