Other ways to change EQ's, sound is s little compressed

Hi there, finally got my Prime Go in Australia. Loving it so far, for someone coming from a turntable background years ago to this, can’t believe how easy it is and its exactly what I was looking for to relive a bit of youth from a does it all device!

One thing I have found is the sound is a little flat. Almost compressed so I have to what the Base EQ up more that I would have expected. I’ve played around with different tracks, mostly 360KPS and Tidal HQ. There are no filters or effects accidentally on. Any other suggestions.

Maybe it is what it is. Have tried a few seperate speakers. Any suggestions?
