If you get a kick from your laptop, that’s just your ears/brain adapting. THAT is what “break in” really is from speakers, electronics, cartridges.
Nope. THAT is what happens when great music is performed by major talent.
I’m sure you don’t really mean to say you know my own personal experience. We never met. Even if we had, that would be like telling me you know I don’t really love my wife. It would be unspeakably rude, arrogant, and ignorant. That would be just about the lowest worst thing a man could be.
Or it could be you meant to say you aren’t able to hear, and your brain is slow adapting. In that case who am I to argue? You're the expert.
