First, beware of casual comments that this streaming service sounds better than that one, it is extremely difficult to impossible to tell unless the differences are huge by doing a non-level matched, sighted test (where compare say A and B but know which is which while you're listening). It's very hard to level match to within 0.1 dB which is required, as the human ear perceives small differences in loudness as quality differences rather than loudness differences. So, take any opinions of "I compared Streaming Service with CD and CD was much better" with a huge grain of salt. Take them for what they are, a person's opinion, including the following! 🙂
I personally use Spotify Premium, running at 360kbs. I find the sound quality impossible to tell from CD even without level matching. Plus I really like the depth of the music catalog Spotify has, the interface is easy to use, and the radio channels are great. I have one I started off with years ago, a jazz one based off of a Grant Green album. By hitting the thumbs up and down buttons over time, it has become wonderfully adapted to my tastes. They also have various jazz playlists they've recommended to me based on that which have been spot on.
As for quality, once early on I was listening to the album "Mingus: Ah Um" specifically to the song "Goodbye Pork Pie Hat." I was certain I heard distortion on the slow, solo saxophone, so I put headphones on to get a closer listen. Not distortion, but the sound of air moving through the very close miked and softly played sax, it's there on my CD of it as well. So, thought I had a "gotcha" moment for the encoding, but it was accurately reproducing a very low level sound.
Anyway, I'm quite happy with Spotify, your mileage may vary of course, and I'm sure you'll get other opinions, pro and con. Hope you find one you enjoy and are happy with. BTW, I stream Spotify to an Auralic Aries Mini, which replaced a balky Playmaker, using an iPad or iPhone depending.
