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


I've recently set up Audirvana, choosing over Roon due to Roon's higher cost.
Seems like Audirvana's sound quality is considered to be high.

Does anyone have any experience comparing sound quality of Audirvana vs Roon or other players?
I use Audirvana to play purchased FLAC's, ripped FLAC's, and also Tidal HiFi from my Mac Mini with Fusion Drive connected via USB.
Looking for input from those who may have taken the trouble to compare.  I for one didn't notice a difference, but I am planning to upgrade my system shortly and differences could possibly become apparent as a result.

I got rid of A+ a couple of years ago for 2 main reasons:
the lack of a nice GUI 
The necessity of placing the Mac in the audio room and using usb to the dac

when I switched, Roon was superior in sq and of course the GUI. I have heard rumblings that 3.5 is a step up in sq and they have a nice GUI now. Unless A+ has the ability for me to have my Mac in another room than my audio room and allowing me to access my dac they Ethernet, A+ is a non-starter for me. Roon provides endpoints which gives you tremendous flexibility and allows you to stay away from the inferior usb connection
I also switched from A+ to Roon a couple of years ago for the same reasons.  Last year I bought the lifetime subscription to Roon, I was so convinced about its superior SQ, compared with A+.

However A+ 3.5 has changed everything on my setup.  It sounds better than Roon.  I use Roon these days mainly for its wonderful radio, connected to Tidal. And yes, the GUI is great.  But on those occasions when I really want to listen to my music, I go A+ 3.5.  For me, the difference is component level - using no filters or upsampling on either.

The New Roon update is fantastic. So many new features. Best update they have ever done by a long shot. Wow!
