I have seen a few people comment that they hear a difference between Roon and other apps. Before I started using Roon a few years ago, I was using jriver and didn't notice any change in SQ switching to Roon. At the time, I was using a Windows PC as my media server, and my system was not as good as it is today, so this could have been obscuring the differences.
Since then, I have completely changed my system - literally every component - except Roon. My system is dramatically better than it was several years ago, but each upgrade has been very easy to discern (some more than others, of course). I can't say for sure that Roon is as good as other streaming systems SQ-wise, but it sure sounds good to me on my system and doesn't seem to be limiting my ability to make improvements through component changes.
And while I love to change things in my system to experience the differences, I have absolutely no interest in giving up Roon.
