Youtube audiophile hi res sounds MUCH better than my Eversolo streamer

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?

There does often seem to be some phantom processing going with various media.  Radio and Sat sound highly bass boosted at times.

YouTube audio is lossy and compressed, not unlike an mp3 file. That can make the music sound "punchy" and some people prefer that quality.
