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 have Audirvana + 3.5.10. I recently tried Roon (14-day trial). I love the multi-device and library management features of Roon. Very easy to setup. I also like how it automatically combines duplicates so that only the highest resolution shows in library. However, I just did a comparison with 3 different songs and Audirvana + beat Roon each time. Roon's soundstage is a bit more flat. I tried Indian fusion, R.E.M.'s automatic for the people in 192/24, and Mariah Carey's One Sweet Day just to have several different genre. Audirvana+ had more robust sound and better soundstage on each one. 
I have completely changed my mind on this question since the arrival of Audirvana 3.5. I have a lifetime subscription to Roon so this is a dilemma. Over the past two weeks I’ve been going back and forth between the two platforms but it’s clear to me that Audirvana has surpassed Roon in a significant way. As things stand, I’ll listen to Roon radio but when I really want to *listen* it’s worth the hassle to switch on Audirvana. It’s that clear and that much better.

I listen to bit perfect native files. No upsampling. Roon via Sonic Tranporter. Audirvana from my MacBook Pro. Both feeding an upgraded microrendu.

Just compared again using Pink Floyd's Division Bell 96/24 HD Tracks Download ("Poles Apart"). Audirvana has a more robust sound stage. Roon is good, but Audirvana is just GREAT. 
Where Roon is better: gapless playback between tracks (Pink Floyd albums are intended to play seamlessly between tracks as one continuation and Audirvana has a gap between tracks), Roon radio, user interface with loads of features, multiple zones, streaming from one library to various devices simultaneously. Keep in mind, Roon has many options for filters and maybe adjusting these can improve sound quality. Not sure. 
i use A+. i tried as I had an all 3xx JBL system and the 310s subwoofer would not integrate properly... timing was off and i could not get this squared away.. i tried all the switches and moved the subwoofer 4 times... nothing worked. i installed A+ and it took care of the issue.
