I'm in Tidal now. Good choice!

Like all sources of music it depends mostly on the masters - always a mixed bag. The deluxe edition of Led Zeppelin on Tidal is excellent.

i don't listen much of mainstream and that's the only concern. which tunes i'll be able to listen to in "full hd" ?
all?
few?
several?

I have a HiFi membership, which gives access to close to all of the Tidal library in lossless format. On my system, Tidal lossless sounds better than CD. A modest but rapidly growing selection are in MQA format, which is discernably superior to lossless and CD to my ears. There were a recent thread on MQA, on which I believe the majority of Audiogoners posted similar views.

If only they didn’t push the jz Crap so hard. Otherwise it’s great.

I have the Spotify premium membership, but will cancel before my Tidal trial membership expires. Be cognizant that if you make your payments/set up up via the Apple App Store you will pay a lot more ($20 vs $26 a month). You can fix this any time by adding your credit card info to your account on Tidal.com, followed by removing your credit card from the app side. Although the social/sharing aspect is much more developed on Spotify the sound quality and overall vastness of selection in Tidal is superior to Spotify (Hi-Fi membership). I plan to run in through a Blue Sound Node 2 I just purchased. I’m looking forward to soon testing MQA as well on my dipole Apogee Acoustics Dueatta Signature Series II speakers. They are very revealing of source material sound engineering flaws. I don’t care for the corporate record industry using MQA as a way to extort money at every step, but as a consumer, if the sound quality is noticeably better I’ll delve into MQA. I’ll keep you posted.
