I recommend the Monitor Audio Silver 500 speakers.

They run around $2500 per pair and are excellent.

The Vandersteen Model 2CE Signature is also excellent in this range.

In any case, you need floorstanding speakers to get where you want to go.

I have KEF LS50s paired with a Peachtree Nova 150, Marantz CD Player and a Project Debut turntable. We recently moved to a bigger house where music being too loud is no longer a problem. I mostly listen to classical, the LS50s with the Peachtree work well but I'd like something with a bit more power, a system that can play really loud and maintain clarity. 90% of my listening is vinyl. I'm willing to spend 2-3k extra - suggestions?
