Need a Streamer

Are you sure it isn’t a Tidal thing, if Qobuz sounds ok?  I would try to listen to the offending Tidal tracks on another streamer and compare the same tracks on Qobuz

I also have the BDP-3, which I think is a terrific streamer. I think it plays best with Qobuz.

For occasional or intermittent sound quality problems, check the source of the recording first... it could be the streaming service or just a crappy recording/mix to start with.  

Garbage in... Garbage out. 

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.
