Looking for seperates under $5k~

McIntosh MA6900.  Or any from MA6500 and up.  Or Mac pre and power amp. In that price range you have your cake and still have money left over for dinner.

+1 for the odysseys. The Candela hybrid pre is very smooth and detailed and a pair of Khartago Extreme monoblocks will still keep within your budget. Factory direct and extremely clean/ solid build have them playing way over their price point. 

Also Klaus and the guys are incredibly accessible and helpful; great product support.  Even if your not the 1st owner.

I have heard the B&W's sound great with Hegel separates. Good luck 

Used Pass Labs..
250.5 amp and an X-1 preamp...
hard to beat.

I have b&w 803N and I'm running a Primaluna Dialogue HP. List is around $4k, so it's within budget. You don't find them used very often, because people don't tend to part with them. If you don't have a local dealer, I can recommend someone. PM me. 

I think it's an awesome match. As an integrated, you save the extra interconnects as mentioned above. I highly recommend the pairing!
