I have three Bluesound nodes (exercise room, guest cottage, kitchen). Two are the older version of the Node 2 and one is the latest. I run Tidal, Spotify, and IDagio through them, and have never had the issue you describe. Either you got a lemon or their's some setting that got switched, or just some loose connection. In any case their service Dept will help you track down the problem or replace.
Just got a new Bluesound Node. Very disappointed!
I got the BSN to run to my NAD M51 DAC and everything sound like the treble has been turned up +10db. The bass is also weak. I use Qobuz and Tidal and both sound the exact same way. I can listen to cd’s is my Oppo of the same music with no problem.
what gives, is it really this bad?
