Hey OP - can you clarify is it just LZ or pretty much all classic rock. MC’s theory might be right if it’s just LZ but if it’s all/most/ a significant portion of classic rock then his theory doesn’t work. I know MC has a strong bias against streaming and that often seems to cloud his judgement. Also if this was the issue wouldn’t everyone streaming from Tidal experience this problem?
I had a similar issue recently though it wasn't with classic rock - rather it was just with certain recordings. After looking at interconnect issues and tightening my speaker drivers to no avail I finally realized the DAC I was using, in certain instances, was putting out too much voltage for my pre-amp to handle. Instead of using full output from my DAC I turned it down (randomly to 83/100) and the problem was solved. Not sure if this could be your issue as well.
