Need a Streamer

Brightness is more likely to come from speakers, bad room acoustics, or bad source material than from a streamer. I agree with others: try Qobuz to see if that may help. Also, tell us about the rest of your chain (especially speakers) and your room acoustics.

If looking for a very-good interface and a warmer perspective innuos is up there 

theZenith has 3 separate power supplies lots of built in isolation

And use premium  Mlytic capacitors for a warmer presentation well worth checking out.

What about inniuos phoenix Would that be a

good addition

More recordings I listen to thinking specific recordings

B&w 800 Matrix speakers Tubes Highs  Krell lows

Audible illusions pre

krell

If you end up  with a new one be sure and compare head to head and give us your thoughts before you unload the loser.  

Poorly recorded source material, bad room acoustics, bright speakers. You can change a streamer but that’s not going to fix your problem.
