Youtube audiophile hi res sounds MUCH better than my Eversolo streamer

You may very well be on to something. HIFI Rose has the youtube music app included on its streamers and many owners have the same experience to their surprise the experience is excellent and with the added benefit of the vid playing in the screen *if you consider that a plus. I own the A8 also (excellent streamer) and I find Amazon Music to be far superior to Qobuz across the board on my A8 despite Qobuz being touted as the best audiophile streaming quality vs other streaming services by many.  Trust your ears.

I would recommend using Audirvāna with Tidal, it will give you a noticeable better sound quality.

I returned my A8 because it just didn't seem to hold up to the hype.

I'd want to see a link to a YouTube video as an example. 

Are you referring to clips where the user mics a system playing back some track through a system?

Another good reason to own and play CD's - and DVD's! Who knows what processing the music/film data goes through before it's streamed?
