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.
Need a Streamer
Have a BrystonDP3. Sometimes Tital comes thru Bright side. Running into a Bryston Bda3
I Only Stream Tital/Gobuz.
