Building new system starting with power amp. What would you choose ?

This is not how it usually happens, but what if you simply must have a particular amp and then move with upgrades in both directions? Let's assume that the only source will be RTR deck, so no preamp will be needed.
The price range..how about $15k new or used ?
This is a hypothetical exercise, I am personally not prepared for that yet. However, it would be, theoretically, perfect minimalist audiophile set-up. 
I myself would probably choose either Lamm monoblocks or Gryphon stereo power amp, both used of course.

Anyway, I do have speakers in my mind that I would consider first, if I could find them used - Kharma.

My fantasy amp brand is NAGRA. If I win the lottery, I want to have all-Nagra electronics.

Nagra. Excellent choice indeed.

Both your initial choices are great, although I would look for the Lamm first before moving to Gryphon.

 Personally I would never start with an amp. If already knowing the budget and room: I'd start with speakers.
 That aside, and playing along, if I were to start with an amp already knowing the lone source and without a preamp, i.e. RTR deck,: I would seek out an an amp with an input impedance, and sensitivity for maximum output that would suitably match the output impedance and voltage output of said lone source (RTR deck) with as much power as I might need.
