Tidal vs Quobuz

Tried both and thought SQ on Quohbuzz (Like that misspelling?) was a bit better. Naturally the ultra high res files do sound better.

Still pondering Roon vs Qobuz but that's a "champaign problem".

Quohbuzz haha.  Really good input from everyone, thanks for turning this into a good thread!  
I’m an exclusive streamer because of the convenience and how many new artists/songs/albums I’m able to discover.  Honestly if it weren’t for streaming I would have never gotten into jazz the way I have in the last year.  
The lesson I have learned from my HiFi journey that started only about 2 years ago is that to my ears, the music can only sound as good as the original source (cables, mics, studio acoustics, amps, mix, mastering, etc). I have found that each service from Amazon to Quohbusz (lol) sounds good and the benefit of the high res is hardly noticeable (again only to my ears).  Instead of dropping huge cash on a really expensive ($5k+) streamer Id rather make improvements to the speakers and power amplifiers, that’s where you actually get perceive sound changes.  My option.  
What a fun hobby this is!

@gearginder,
I’m sure it all depends on your listening preferences but here is my take. I went from Spotify to Tidal. I had used solely Spotify for 5+ years. Loved the sound quality upgrade of Tidal but hated loosing access to so many tracks. So I kept both. I subscribed to Amazon HD and have never looked back. After two months I have actually canceled my Spotify subscription. Amazon has a much better library than Tidal and has a large selection of High Res albums. No MQA nonsense to fool with. I really recommend giving Amazon HD a trial run if you have not checked it out yet.

To: geargrinder,
I’ve followed an identical path very similar to you, Spotify for 4+ years, Tidal Hi-Fi and Qobuz for 1yr, and now Amazon HD since it was released. Using Amazon HD for CD quality, intentionally. No DSD/MQA. Formerly using PlayFi middleware app for my streamer, now back to AirPlay/2 which fully supports Lossless CD quality transfer rate. Amazing catalog with Amazon HD, like Spotify, yet I’m always going back once a year to revalidate sound quality of each of the former Service Providers. And Spotify dragging behind, still not going to Lossless since the 2017 lossless beta test they tried for a short time. Bean counters must be holding back the engineers there.

Connectivity/Middleware:
Curious to know if you have thoroughly compared sound using the different connectivity and protocol methods offered. Clearly Spotify Connect was nice, and now Tidal has something similar with Tidal Connect. Playing with AirPlay/2 enabled streamers, connecting to the native streaming service application which works better now than what I recall a few years ago. AirPlay2 streams Lossless well, as we know. I read something (unconfirmed) that some service providers (may) license AirPlay under the covers for their application connectivity method...I have no proof of that. Others may know better or can confirm. 

Question:
Since using Amazon HD, have you by chance gone back and compared "sound quality", and sound stage depth with something like Tidal Connect? I have not, yet. I’m listening for any degradation with AirPlay2.

Any in-depth testing and sound test companions you can share would be appreciated. Thanks.

I find the Qobuz sound quality makes IHT the winner of these options having tried several.  Availability of music is good enough that the better quality trumps the inconvenience of not having absolutely everything.  I believe their catalogue grows all the time so I guess they’ll get there. I access it through the Linn app and my Klimax DS streamer. I have B&W 800 D3s with 4 mono block Linn solos bi-amped through them and Tellurium Silver II cable - The quality is so satisfying that it can bring tears to my eyes.  I would say from this experience that top quality source material is fundamental if you’re interested in the quality of your listening.  Garbage in, garbage out can’t be got round.  

Sorry.  “IHT” should read “it”
