Sorry to say that you are compare apple to orange.
If you want to compare SQ you should compare with jPlay, HQPlayer, XXHighend just to name a few. and each of them has Pro and Con just like JRiver.
However, if you want to compare music Management. Roon is second to none that currently existing. And just to say Roon might be a new name but people who did Sooloo 10 years ago and also HP Music.
Hope this clear things out.
