My Question or Issue

I simply want to know how youtube can be better than Spotify's high quality enabled stream.

I am referring specifically to one track I believe shows it, Home - Resonance:
https://www.youtube.com/watch?v=8GW6sLrK40k

Compare this to the Spotify version. The sound is clearly "fuller" and deeper on youtube. I tried 2 links and they are both fuller. 

Why is this, when technically, Spotify's stream should be better? I've enabled high quality stream. Is there anything else I can do?

I totally agree with you! I am testing Youtube Music/Premium and in the next days i will compare with Apple Music. Actually Spotify Audio Quality is worse than Youtube Music as a exemple.
