This really should be a case by case scenario discussion. Definitely not a black and white topic. Especially with the advent of some very nice active component “systems” now available, and being designed by several different companies - boutique and commercial.
I love the sonic changes produced by different amps in terms of their compatibility with my components upstream. But I’d also really love to try some Buchardt A500 or A700’s, KEF LS 60’s (when I could afford the luxury of additional systems) or anything that might turn up in the near future with interesting offerings and superb design.
Genelec’s are interesting to me, as they tend to cross that threshold into the tonal aspect of home audio of listening. Not just a cold/analytical studio monitor. But I digress.
