Thanks for all the thoughtful responses.
Horns sound great to me for a bit, but they get tiresome - fatiguing. Additionally i don't love their directionality.
I'll look into ATC - any particular models as a good value.
Also considering Omega Alnico Monitors - anyone with experience on their sound signature?
Or the KEF R3 Meta?
I'm wondering also if my current speakers are too big for my room (11.5' D x 12.5 W x 10.5' H, with open spaces on both sides of the width. Couch at the back wall. Tweeters are approx 2ft from the front wall)
