Audirvana Plus vs Roon - High Sound Quality at Lower Cost?

I do run Audirvana on my PC.  However, I prefer not to use my PC in my Audio System, and that is why I use renderers instead of the PC with Audirvana.
I have been using Bluesound, but recently I had a problem where I could not use it for a month.  I went back to controlling my NAS with Audirvana and my PC for that time.  It sounds truly excellent and the App isn’t bad, but it was a problem if I wanted to use the PC for something else, and I get tired of the Computer boot up, with the Apple notifications, etc

I'll put in another vote for Audirvana.  I use it exclusively on a mac mini server and run it from the very good iPad app.  Mostly playing local files stored on a NAS but I do use Tidal some.  You don't have total control of A+ from the app but it is excellent for playback.  Sound quality is excellent.

I have used Roon a lot and I think the interface is terrible.  It is so convoluted and cumbersome to navigate.  To me, simplicity is king and A+ is way way ahead in this regard.  Roon does have a little more flexibility in terms of browsing Tidal, but I don't think it is fun to use.  FWIW this is coming from someone age 33 so it is not like I am a geezer struggling to use new technology!  

I am running a MacBook Pro with a low end DAC (no MQA or DSD) over USB. Solid State 1TB storage. Audirvana and Tidal as well as local files. I feel my best next purchase for SQ will be the NAD C 658... I am using  AirPulse Model 1 powered speakers with balanced inputs... everthing sounds great.
