Spotify or Pandora

Just went on Tidal web site.  OK, ... so walk me through how I get the Tidal music into my linestage.  I do not have a DAC, other than what is in my PC.  So the music signal from the PC to the linestage has to be in analogue format.

So, how do I connect my PC to my linestage in analogue mode.  Is there a UBC jack to SE or XLR/BAL type connector cord to make the connection?  Is the UBC jack a digital output? If so, would I have to use the headphone output jack of my PC??  But how do I connect that to the input jacks of my linestage (SE or XLR/BAL)??

Also, is the DAC in my PC inferior to a separate stand-alone DAC unit? If so, how much SQ  would I lose by not having a dedicated DAC?

I am a older member of the baby boomer generation.  So this is all new to me.

Thanks.

Yes, you should get a separate DAC. 
If you want something inexpensive, get a Bluesound Node. It has great connectivity with other apps and you can buy a better DAC, should you want to.
I use the Bluesound with an Ayre Codex, and I think it a very good path to streaming music.

Instead of Pandora music, I’d like to listen to music, playlists from Spotify streaming services, since it gives me the free access to over 35 million songs.
Although I didn’t like to use Spotify before, since there is no way for me to download Spotify files for offline listening. Fortunately, I found out the professional Spotify to MP3 Converter for Mac from  https://www.audfree.com/spotify-music-converter-mac/ that can help me download and convert Spotify tracks as MP3 even without Premium subscription.

Glad I found this thread today. I was a Pandora early adopter, and been on their first level upgrade ($3.99/mo for ad free) for awhile. Because of radio style restrictions (even more since they introduced premium) I was looking at possible upgrade.

So, long story not as long, set-up trial accounts with Tidal and Spotify today. I've been listening  at work using very basic Sony headphones. IMHO Tidal clearly superior SQ compared to either Spotify or Pandora. Actually I can't tell much difference between those two.

Looking forward to running Tidal into DAC at home and listening through much higher quality cans. Just my 2 cents.

Happy Listening!
