Roon Streaming Service actually Degrades the sound

Objective measurements are a tool to get better sound quality but they don’t constitute better sound quality. Measurements do not represent sound quality in its totality. In the end if it sounds better, it is better. Or if it sounds worse, it is worse.

Agreed. If Roon sounds worse to the streamer maker, then to them it is worse. We all have personal truths. We also benefit from experience, which requires an open mind to try different things. If the OP wants to decide for themself if Roon degrades sound quality, they can try different software and compare. They (and anyone in general) would be better served by doing so than taking anothers word for truth.

I  have heard Aurender having a bias against Roon,

 your server,dac hub has a lot to do with the final outcome .

my dedicated server I built ,uptone audio hub ,New Denafrips Terminator2, with reclocker is incredibly good And is very natural sounding ,=Analog .

iits actually a T+  for less $$  for  under $5 k  a Steal, prices going up Tonight though what % we will see.

My ROON Core is located in my ROON Nucleus Rev B. All it does is allow me to choose between which music on Tidal or Qobuz that I would like to hear. The Nucleus has its own linear power supply, and has RFI eliminating filters front and back, which makes for a pretty clean signal before it travels into my Chord Hugo M Scaler and then to my TT2 DAC. Does it sound as good as any another streaming software being run through a dCS Vivaldi stack? Probably not. But it does sound as good as most high end CD transport or vinyl system that I’ve heard. What makes ROON great is its convenience and ease of use. Quibbling about perceived sound quality issues up in this rarified audiophile air is mildly interesting, but not the most important thing to discuss IMO. I don’t believe that the sound engineers at ROON are trying to cut any corners when it comes to providing the best product possible. But by all means if something sounds better to you, then use it and don’t look back. 

Debate over the best sounding player software has existed since digital audio playback became more mainstream. Roon is just another contender in the game. I suppose its popularity has made it an easy target. I don't see nearly the same discussion over the sound quality of Lightning DS, Lumin OS, Aurender Conductor, and other proprietary software.

What is more agreeable is that Roon is one of (if not the best) library management tools available. It seamlessly allows a user to access both local media and streams from Tidal and Qobuz in an elegant and user-friendly way.

"I suppose its popularity has made it an easy target."

I think you're spot-on with this. People love to bring down and bad-mouth popular products, trends, even other people.
