Spotify vs other streaming services

??$9.99 a month on Tidal gives you the 16/44 redbook quality streaming, same on Deezer for same price.Well above 320kb service level.
But I guess Quboz will be here very soon so some will see how that works out for them.I ran it on a trial but their rock catalogue is very limited compared to Tidal so I will be sticking with Tidal HiFi for now.

Tidal website states $9.99 for 320 kbps. $19.99 for 1411kbps ( full redbook).  Various other family and student plans 

for some reason Tidal calls their lower quality option "Premium"...

OK I am new to streaming and using Spotify. I use a Music Fidelity V90 DAC so does it matter the quality of the streaming if one is using a separate DAC? 

What matters is the quality of the DAC and system. The V90 is certainly good enough to make the sound quality differences obvious.
