Integrated for B&W 805 Signatures

Ok guys, simple question, I'd appreciate some input on those that have some knowledge here. I recently sold everything and started over, acquiring a pair of these 805 Signatures and I'm looking for a good integrated. Price is important, but flexable. Popular one's I've read up on:

1) Classe CAP-151 (new CAP-2200 is pretty pricy)
2) McIntosh 6500
3) Plinius 9100
4) Music Hall Mambo
5) Musical Fidelity
6) Many tubed players, but have 2 under 3yrs old.

Thanks.

Dave
