Integrated amp and CD player for the new B&W 805S?

I have the new B&W 805S. I'd like to get Integrated amp(or separate amps) which sounds(or sound) good, can drive them successfully and is(or are) matched well with them. I'd like to get CD player which sounds good and is matched well with the new B&W 805S and the integrated amp(or the separate amps), too.

My mostly listening music is symphony, orchestral, concerto and opera. My budget for integrated amp(or separate amps) and CD player is under $5K. Both solid-state amp and tube amp are welcome. Both new and used are welcome.

Thanks.
