My summary of this thread is that the term ’musical’ is not a good term to describe sound or equipment characteristics. It appears to have multiple different means to different people.
We’ve been getting nice reviews on our products for decades now. ’Musical’ is a word easily applied. So I have concluded that a benign distortion character is paramount to equipment being musical and the evidence seems to support that.
What people choose to play on that equipment is a different matter- some of which some people might regard as musical while others might not. So the topic, IMO, is bit too broad in the context of this thread. I’ve only been posting about equipment and how that can be musical, while others have been considering actual music and the way taste might affect your appreciation of it.
