Have had Spotify Premium now for a few years and wanted something similar which offered CD/FLAC quality streaming - which this does - and so for audiophiles, its a welcome addition to the world if music streaming.
There is, though, a BIG difference in the subscription price: this is - if you choose the CD-quality streaming option - about twice as expensive as, say, Spotify.
There are also some niggles with the software itself, which Qobuz should really address for the price one has to pay. Having said that, the user interface is pretty good.
As far as selection goes, its behind Spotify in that area, but is still pretty impressive.
In conclusion - If Qobuz can bring their high-quality streaming subscription price down closer to the price of Spotify premium, they will TOTALLY nail it.
