I have had both Tidal and Qobuz at the same time and Qobuz wins the SQ contest IMO.
I prefer Qobuz CD quality to Tidal.
Also Tidals MQA "high rez" sounds identical to me to their regular 16 bit flac. Only using their ?Win 10 app to "unfold"
Qobuz high rez sound the real deal and is worth the $25 a month IF they can improve the US music library.
So at this point I am a former Tidal subscriber
Qobuz works great on my Android 9 phone, I can download real high rez for playbook off line.
CD quality for T-mobiles network streaming seems to be the practical limit, but highrez streaming works great on fast home wifi.
