Looking for seperates under $5k~

Okay, I'll bite.
First,I assume you are buying used.

As a 'bang for buck' guy, I recommend a McCormack amp and Preamp.
A DNA-.5 and a RLD pre could be had for a little over $1K and upgraded by SMc for under your $5K total.

If you're looking new, I just tried 805s (whatever the new Diamond version is) with an Exposure 3010S2 preamp/power amp.  Worked beautifully, so might be worth a look.  The 3010S2 pre and power are about $3800 new. 

Are you dead set on separates?  A McIntosh integrated would match up very well with your speakers. Some believe that the Mc integrated amps easily compete with separates.  Plus you save yourself the expense of another power cable and pair of interconnects.  I love my Mc integrated and if you can find a MA8000 for under $5000(and I think you can), you may not ever want for more.  My two cents, good luck.
