I use a 2014 Mac mini w/ Kodi in the living room system and a Raspberry Pi 3 B+ w/ moOde in the basement system. I haven’t heard a compelling reason to change either out. The Mac stores all the music in a shared folder which is mounted in moOde. I control everything from my phone or a browser and can cast Qobuz or YouTube Music from my phone to either setup without a hitch.
The streamer’s job is to send the bits to the DAC intact. Digital errors are fairly noticeable - for some audible examples, have a listen here - link. In my opinion, I think the most important thing about streamers is that they offer the convenience and features you want.
Why not test your Bluesound head to head against the Macbook Pro? Connect both to a system, close your eyes, and have your friend switch between the two. See if you can guess which is which. Try it 10 or 15 times yourself and have your friend write down your guesses, then trade places.
