Sound quality of Roon

Roon is definitely the best overall.  Yes, quirky and unstable with limited support resources, but no doubt an amazing experience when working properly.

the thing is it takes a long time to optimize sound quality with Roon.  And when you benchmark sound quality, you need to use Roon with a streamer.

I must say that I agree with Grannyring, I have tried Roon for many years and it is the best music mgmt software yet available. That said, however, I believe it falls short of the mark as it relates to SQ. Not bad but certainly not setting any benchmarks. That's a shame, because I believe that Roon is capable of making significant improvements in SQ but for whatever reason has not made this a high priority. Now that I said that, let me explain my experience with my system and other high end systems that I listen to frequently from my audiophile friends. My system consists for an Innuos Zenth Mk II SE, Innuos Phoenix reclocker, Optical Module, Etheregen, Ansuz C2 power distribution and cables etc. I have used Roon, Ipeng9, Euphony, Audiavarna (not all on my server) but on other very high end servers with high end LPS. My experience has been that the Innuos OS sounds significantly better than Roon on my server and Euphony sounded better as well on other high end servers I have done critical listing on. The great thing about Innuos as a company, is that they are very committed to continued improvement of their software and hardware; specifically as it relates to function, features and in particular, sound quality. Their customer service is excellent as well. I am pleased with the investment I have made and continue to increase my enjoyment and satisfaction with every new update. I should have mentioned previously, that I am not a dealer, nor have any financial interest in any way with Innuos. I hope this was helpful.

After reading the comments on this post, one thing has become clear.

There is no consensus on the benefits of Roon, in fact, it seems to me that people hear what they want to hear.

My belief is that people subliminally convince themselves that the money they spent was worth it.

I'm not saying that there was or wasn't an improvement. What I am saying is that the person paying for it "wants" to feel that it was money well spent.

I believe that the reality of the situation is that there are a lot of components that are excellent, but looked at individually, aren't significantly better than what the other guy bought.

Think about it.

Every time an OP asks for recommendations for a component, there are dozens of responses from Audiogoners extolling the virtues of component X, Y or Z. To me this is proof that the differences between components is minimal once a certain level is achieved.

@troidelover1499 There's a lot of great insights on here. This topic has been on my mind for the last couple of weeks for other reasons. Here are a couple of thoughts:

1.) I currently use Roon streamed from a dedicated Mac Mini (M1). My current digital setup consists of Roon --> HQPlayer (non-upsampling) --> Curious Cable USB --> Denafrip Hermes DDC --> AudioQuest Carbon HDMI I2S --> Denafrips Terminator II.

2.) Roon is a product that is generalized to work all kinds of different hardware, virtually none of which is optimized for digital audio playback. Jitter is a constant negative variable in digital audio SQ, and many hardware manufacturers (like Apple) aren't necessarily concerned with digital audio playback. Personally, I think the Mac M1 chips sound better than the older Intel chips. 

3.) Jitter IS a problem that virtually all DAC manufacturers address and mitigate with varying degrees of success. Digital-to-Digital converters from manufacturers like iFi and Denafrips can help mitigate that issue a little more. A DDC is something that I think can help improve the SQ of a Roon music player. 

4.) It is true that some streamer manufacturers may focus their hardware on the elimination of jitter and producing a clean audio stream for the DAC, and thus higher sound quality. However, I suspect that most of those manufacturers focus their efforts first on the user experience (since it is the most visible), and second on the hardware. I also think there are fewer manufacturers that put a great deal of effort into both of those things, and can produce streamers with better SQ results than Roon. 

5.) For me, Roon and HQPlayer on an M1 Mac platform give a lot of flexibility. I currently use HQPlayer as the transport of sorts (without upsampling, which I know is weird) between Roon and my DDC because I think it sounds better. I'm somewhat conflicted on upsampling right now, but at a minimum what I can say is that it can give a few more "flavors" of sound to choose from. That said, many of those kinds of options are just out of the question with a dedicated streamer.

For now, this setup works really well for me, but I'm always on the lookout for something better. Best of luck. 

@past This sounds right to me, makes sense and backs up what many experts have told me during my research, the DAC makes the biggest difference to SQ.
