Spotify sounds compressed

So now that I have more time to mess around with things like this, I started using Spotify and went premium right away. But it sounds compressed. I looked in the settings and the high quality streaming switch is on. When I switch it off, there is no change in sound.
I have my Samsung tablet hooked up to the preamp using it as the source while using my Asus notebook to manage things. The settings on the tablet are set to receive extreme quality signals. When I listen to Radio Tunes the signal sounds much better with extended highs and very deep lows. It just seems to me that the Spotify highs are compressed, not very extended. Is this the norm? I think Spotify is excellent for finding new music, but it doesn't sound the best.
Spotify, unless it's changed, does NOT offer high quality streaming like Tidal or Deezer.

It's highest quality is 320K/MP3. Tidal offers 16/44.1 which is 1411kbps. That is over 4 times the resolution of Spotify/Beats/Rhapsody.
Something else is wrong I have heard Spotify premium on my system and it sounded very good. It certainly isn't compressed. I do have both Tidal and Classicsonline which are both better than spotify but not by that much. Can you try streaming directly from the ASUS?
Mofi, I think I remember reading about Spotify having less quality than others.

Arh, If something else is wrong, I don't know what it could be. Radio Tunes sounds excellent, Spotify not so good. I don't have the capability to hook the Asus up to the system. I'd have to buy another cable, and I just purchased the interconnect, an Audioquest Big Sur 3.5mm to rca, for using the tablet. I guess I'll look into an adapter for giving it a try.

I'm also going to look into Tidal to compare the two. I have time since I've just started using Spotify on a trial basis.

Thanks. will LOVE Tidal. I have been a user since day 1 and it really is indeed an incredible service.

On my system, it trounces Spotify/Beats/Rhapsody. While I agree with Arh that the others can sound decent, Tidal is in a different league altogether.
I started to load the app on my tablet, but decided against it. Since there is no connect feature I won't be able to use the notebook to navigate, plus a lot of the reviews tell of many problems. No a very good rating. I believe it does sound a heck of a lot better than Spotify, but with all of the negative reviews and twice the cost, no connect option, etc., I think I'll pass.
Will see about connecting the Asus up to verify it's not the tablet, but Spotify.
The only reason I started with this was because the station I was listening to was starting to get repetitive. Can always change the channel for a while. This only costs $4.99/mo. for the premium service.
Using the headphone jack on your tablet isn't the best way to get music to your preamp.
If you can't hear a difference between standard and premium, something is wrong. I can readily hear the difference when I switch streaming resolutions on spotify.
Pootify sounds compressed because it IS. 320k MP3 is very good for iPhones and such, but it is most certainly NOT anywhere near hi-res...
"Pootify"? Seriously?! Man, I REALLY need my morning cuppa...
He is right - spotify is poop compared to Tidal/Deezer. They sound great through ear buds. Real speakers or head phones, not so much.
A$280 - It's been a while since I started subscribing to Spotify's Premium service. Mostly, it sounds really good to me. I use USB 2.0 out from a MacBook Air to upsampling MF 192 SPDIF converter to Gungnir DAC to pre-amp. Doesn't sound compressed to me BUT I do notice not all recordings in the Spotify library are of equal sound quality. Some are definitely better than others SQ-wise (might be Spotify, might just be audio quality of the original music). Would you mind posting tracks or albums that sound bad/compressed? I and others could check them out too..."see" what you are hearing (or not). Maybe include a couple that sound good to you. Just a thought. You can copy and paste the Spotify URL by right clicking on a track or album. An album that sounded exceptional to me was Fabiano Araujo's "Rheomusi". Here is the Spotify URL (from a Mac) to it: spotify:album:3sGE91vWhQC1xKJQkOb4eh
Ghosthouse, all of the tracks sound compressed. I just loaded Tidal on the tablet, picked a couple favorites, checked all of the settings, and the quality blows Spotify away. Spotify is just sub-par. I thought I may be having trouble with my notebook so I updated the audio drivers to be sure they were working right. Had issues with setting up payment for Tidal, but after a while it finally took. I know using the headphone jack to the preamp isn't the best, but it sounds pretty fine for casual listening.
I believe I'll keep Spotify free just to search for new music and use Tidal as the player.
Thanks Mofi.
Abuck...glad to hear you went through with trying Tidal. I think you will really enjoy it.
Glad you are enjoying the SQ on Tidal, A$280. Don't know your taste in music, but regardless of source, Rheomusi is a pretty nice recording.
Thanks guys. I'll be sure to check out Rheomusi. Right now I'm looking at an inexpensive DAC for hooking up the notebook. Something like a Musical Fidelity V90 or a Music Hall dac15.2 which both cost the same at AA. Don't want to spend a lot at first. May upgrade later.
Ghosthouse, Thanks for the tip. I like very much.
A$280 - You are very welcome. Pleased you like it.
I love Spotify for background music. I have it all over the house and at the pool. Makes the house happy. When I want serious listening I go to Vinyl/cd
Been using Spotify premium for awhile and am quite happy. Mine is run via airport express toslink cable to dac/ preamp. As others said not all recordings equal. Try searching in Spotify for audiophile test track playlist to sample some better recordings. Also try linn radio on the web for good quality streaming music.
Just got the dac hooked back up. Will look into Linn Radio.
Torxx, thanks for the Linn radio suggestion. 320kbs sounds pretty fine, plus I like the variety.
I'm streaming Spotify through an Asus wifi/Denon through Airplay, and it sounds fine. I only listen to it for background music throughout the house, but it certainly is acceptable.

Spotify vs Tidal.

Is there a sonic difference. "Absolutely."

But if your using very very  good Quality DAC/Pre-Amp/Amp & speakers.

The EAR is more easily Pleased! with either streamer service.

I subscribe to both.  Now on Spotify: Classical. Violins little less timber & sweetness. Horns a little less brassee!. Piano not all that much. The high Freq range instruments is were the missing kbps are lost anyway.

Female voice depends widely on the recording. Ex: Diana Krall

Tidal slightly less husky. 

Heir's is all there. Just a little less throaty with Spotify.

My bottom line is." I can find no great loss of  measureable pleasure when playing Spotify. Why both services. Easy, each has recordings the other doesn't offer. If I want to hear an old artist.

                     K-BPS isn't going to stop or effect me!!.

Really sounds terrible I'm dumping it ASAP!!
I used to have itunes radio delivered by appletv straight into my dac, and it sounded great fo what it was, not to mention free.  Since an imbecile removed the service, i stream spotify through roku and my tv dac, and it does not sound near as good.  It's comparable to pandora....great for discovering music, but frustrating audio-quality wise.  
I'm a premium user for both Spotify and Tidal. If you will compare to Spotify and Tidal, Spotify songs could be little lower than Tidal HiFi but not too bad. Spotify Premium supports 320 kbps audio files which is the same as Tidal's Premium. 
If you'd like to get more high-quality Spotify music, you can get help from a professional Spotify Music Converter Mac, which can not only download Spotify playlist to MP3 but also keeps all ID3 tags as you like. After that, you will not worry about the quality. By the way, you can also choose lossless FLAC, WAV as the output formats.
