@mofojo Big myths die hard. So this does not surprise me- I get pushback on it all the time. But it comes down to something very simple, which is can you find a designer who can say what parameters exactly will favor a certain genre?
I’ve been doing this 45 years and got an engineering degree early on. I know a lot of designers and none of them make any claims to this effect. Since I design amps and preamps I see things a bit differently, thru the eyes of my test equipment. Once that signal is in the amp, the amp does not care what it is, it just amplifies it. I suspect the same thing for speakers- they have no taste, they just move as the amp tells them.
Any tech dude in the manufacturing space seems to think he knows everything there is to know about music (anything he doesn’t know is all one big myth!). Why don’t you have a seat someday and talk to guys like Levinson (too late for the late Schweikert) who actually understands instruments/music? You may gather more insight.
Until then, it is just another case of beating the deadhorse over n over about myths and non-myths.
