+1 KEF. I have the R500s that were a steal on close out a few years ago and to get a meaningful improvement I would have to spend probably 3-4 times as much and then would not have the very condensed thin tower 42" height footprint that I like, that makes for the excellent dispersion and which don't overwhelm the room.
They are on Sympoosium platforms which improved the sound dramatically over the KEF spikes/cups. I have a large open multipurpose den that extends into the kitchen eating area 30 feet or more from where the speakers sit (the back of the speakers are 3 feet from the wall). I listen often from the kitchen or when I am in the kitchen cooking/prep area.
Best listening chair - Ekornes stressless chair - expensive but worth it. First one is still in great shape 15 years old (leather worn out where your head touches with a custom cover, so it will go to one of the kids when they have the space/need). I got another one of the same model in a different color (believe it or not), still in production. It can't be in the optimal listening spot, so the KEFs are great. When I really want to focus on an album playing, I'll sit on a loveseat that is in the optimal position. It's comfortable, just not in the league of the Ekornes.
