B&W are awesome speakers and in my opinion not overrated. The speakers are very sensitive to the upstream components and require very good electronics and cables to sound their best. They will not forgive any weaknesses in the chain. You're aiming at good components so far, but the B&Ws will like some room treatment behind them...corners, seams, etc...
My other suggestion as far as the speakers are for what you're looking for doing is Vienna Acoustics. They will be more forgiving to room conditions and electronics. Take a look at their Strauss and Beethoven Consert Grand.
If you can, go and audition some of these speakers along with the B&Ws.
Also, if you can, go with pre-amp and amp instead of integrated. You get more flexibility this way. Used Sonic Frontiers Line1 tube pre and used McCormack DNA-125 amp should do the trick. With the McCormack amp you can send it for upgrades if you want and turn it into an amazing sounding amp. These 2 pieces used will probably run you close to what you'll pay for Cary integrated.
