I have Qobuz, Tidal and use Roon. To my ears Qobuz has the edge, but there isn't that much in it for files of similar resolutions. Tidal master smears the music with MQA, however, I convert all my music to DSD256, if it is below 96/16 resolution. I tried an MQA DAC, not my music! Google "neil young mqa"
I note that dBpoweramp will now rip a CD to DSD256, a whole CD taking 2Gb, probably the same as 6 CD's in FLAC format. Is there a difference? Not a massive one, but then if I had a Top Naim system, and masses of SSD hard disk storage then I might hear something.
My Roon server is based around an Intel i3, maybe changing it to some higher spec, might make the FLAC to DSD conversion more amicable.
It is worth noting that my #Cymbiosis serviced and upgraded Pink Triangle still has the edge.
