After thinking about it and although I do think the Pulsars will provide some improvements maybe most notably in the bass and possibly in imaging and 3D soundstage they probably are more alike to your speakers than different overall. So if you’re looking for something really good but different I’d look to ATC especially given the music you listen to. Neither the Fritz nor JA speakers can match the power and dynamics of the ATC speakers especially in the all-important midrange, and it really shines on rock although other genres benefit too . Here are some used FYI, but the dealer I linked previously offers returns and a 10% discount so may be a good way to demo and hear what I’m talking about. Since you have a sub the SCM19s could well be fine and quite a bit cheaper than the SCM20s and are probably the sweet spot in the range. Read the reviews that are pretty much all glowing, and they’re also used as reference speakers by several reviewers that says something as well. Anyway…
