Classic rock. Recording / streaming quality? Not sure it is the speakers fault. He might be shooting the messenger. And just because it is Tidal does not mean it will, by default, sound good. Other factors at play. Original recording / mixing quality being at the top of the list. The issue seems pretty obvious to me.
Have not heard mine yet but will post impressions. BTW, I will be streaming classical music, some in lossless flac. Thanks for the input. Best.
