I feel for the OP here. That's a substantial chunk of change to spend to be not happy. I agree with those in here that say give it time, and also if you haven't treated your first reflections with absorption panels, that may be the biggest issue you're having. All that harshness bouncing against the wall is no bueno. After 400 hours of break in if you're still hating the harshness, try some acoustic paneling from GiK acoustics or build your own. Just first reflections (side walls and if you can afford it / have the WAF covered, go for a cloud as well) will make a massive difference when it comes to harshness and intelligibility. Dampening the room is not very costly at all either comparatively.
Don't lose hope my dude! And if after 400 hours and paneling isnt working, sell those babies and get some new B&Ws if you like their sound. Otherwise I agree that you should audition many brands. Rockport, Perlisten and Devore seem to get rave reviews constantly
