I would go with BS9000, purely for looks! (I have the same setup, and it's great!)
BC2 with DVD if you want a complete AV solution.
Before I switched back to B&O I had a very good high-end system. ELac 609 speakers, Pathos endorphin CD player, Pathos Logos amp etc...
But I enjoy listening to my music much more with the B&O system. Yes the old system was better in reproducing mid and high-level details, partly for having "Air motion transformer" trebles instead of the classic dome tweeter B&O uses. But moving down to lower mid and low frequencies, there's probably nothing in this price range of the BL5 that can beat it. The power and control is simply mind-blowing.
I have a masterlink system, and have the BL5 connected to my BV5, but watching TV and movies, I seldom use them this way.
So simply put, I wouldn't go back to my old system, costing just as much, and the Hype that you don't get your money's worth with B&O in sound is just pure BS.
Get the BL5's and BC2, BS9000 or BS5 and enjoy. Use these, because you get a digital out (SPDIF) this way you will feed the BL5's with a uninterrupted digital signal. You can buy a third party CD player, but things like synchronization etc between the speakers come into play, and I actually tried this with a Mac Mini only to find out that my BL5 was a too early model to work in sync using the sync cable from B&O. It's there, but can't be used. 😭 I did ponder more than once about keeping the Endorphin CD player, since it such a beauty: 
But I wanted the whole experience with Masterlink and what not...
