I've been using Qobuz (USA) very heavily for about 6 weeks now, more than I normally would due to being home from work awaiting COVID-19 to pass. Coming from CD's as a source for my system, I am really enjoying the increased realism permitted by the higher resolution files. As for music offerings, I have spent many hours trying to find albums which I own in CD format that are not available on Qobuz with virtually no "success." Far from discovering missing albums, I am instead excited to learn through this search how much more music not already in my physical collection is available from favorite artists.
I have scoured Qobuz's available offerings in most all genres, but admittedly very little modern pop/hip-hop (but don't worry, Dua Lipa's catchy new album is on there!). The word on the street seems to be that Qobuz is only for you if you listen to just classical or jazz. But the collection of music available in Rock, alternative, indie, world, etc. is flawless from my humble (but demanding) perspective. Grateful Dead, Foo fighters, Nirvana, Wilco, Wax Tailor, Bassnectar, Daft Punk, Tiesto, are a few of the artists I have been exploring through qobuz and have found all the albums I own plus all the others I already knew of but don't own plus many other albums that I didn't already know of. AND many of these albums are available in much higher resolution formats than CD quality. Even within the above-mentioned non-classical groups, probably at least 1/4 of their offerings are "hi-res"--higher than CD. If you have a decent system to send these files to, you are going to enjoy the improved sound of these higher than CD tracks. (for reference, my chain: Denafrips Ares II DAC>bottlehead crack amp with quality vintage tubes>Sennheiser 800S).
I'm thinking of boxing my CD transport and putting it in storage now that I have qobuz. It's that overwhelming. Furthermore, the qobuz iphone app is great and now that I can listen to any albums I was listening to before on the go (parties, boat, more popular music when hanging with friends, etc.) but now in CD quality, I have canceled my Apple Music account.
For the cost of a CD or two per month, and minus the cost of apple music, I am truly pleased with Qobuz and would have to give a nearly unqualified recommendation to any and all. Nearly because the computer based software is not flawless. I sometimes have to close qobuz and reopen when it suddenly malfunctions. Sometimes, a track plays in a very "damaged" way -- something equivalent to a scratched cd. Or, a track will display as playing, but no sound is coming out of the speakers. To be fair, this might be in part due to the computer, not the streaming software. But closing and reopening usually fixes this. I would have to use a quality macintosh computer as the streaming source for awhile to know if it is just my often glitchy albeit nearly new Dell computer that is causing these problems.
Also, I emailed the qobuz technical team email address a simple one paragraph question about a network streamer without onboard DAC's that they would recommend/partner with 2 weeks ago and have yet to receive a response. I did have better luck with a different question which I posted to their facebook page, but even that took a week to respond (they did apologize for the delay, but still...)
I should also mention that qobuz is very good at helping me to discover new music through its music suggestions and its "discover" category.
I can't compare to the obvious competitor Tidal, but as I am a cellist and love classical music, all indicators are that Tidal's current meager classical offerings would severely disappoint me...even though their technology that is supposed to remove the ubiquitous ringing recording artifact intrigues me.
In conclusion, once the hi-fi consumer market discovers how great Qobuz is now, I expect it to really dominate. I am thrilled with it thus far and plan to design an audio system for my livingroom with Qobuz as my primary music source.
