What would offer a better value and sound for the price:

KEF LS50 with NAD D 3020

or

B&W 685 S2 with Rotel RA-12

I have a large room and listen to mostly classical with some blues and rock. I don't need a lot of bass and I plan on listening at medium levels. My budget is between $1500 and $2000

Also any suggestions on good integrated amps for the 685 or the LS50 within my budget would be appreciated.

Thanks in advance
