I would really like to see Aurender team up with HQPlayer for the absolute best possible sound quality.
Roon is fun for the pointless connection to all sorts of info many of us are not interested in. Roon also does not sound as good as the Aurender engine itself. It's eye candy at best.
I bought my Aurender player for the excellent sound and build quality. I think this can be improved even more with HQPlayer.
