IMO you’ll find an open baffle speaker most satisfying. I’ve got GR Research NX-Oticas and drive them with a 9 watt 300B tube amp to ear-splitting levels when I’m in the mood for that.
They are kit DIY speakers, but you can find them used or get someone to build them for you. I‘ve listened to several $500k systems and prefer mine.
But in general, I believe you’d love most open baffles if you like Dahlquists.
