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.

Crazy that No one mentions the excellent Sugden A21se. They started it all when it comes to SS class A well over 50 years ago. At $3250, a bargain in my eyes. Pair it with some nice Tannoys and a tubed phono stage and I'm certain you will be very well pleased.
My latest video on the DIY HiFi Life Channel covers the VTV Purifi Amplifier. Stay tuned for my next video where I show how to upgrade this amp as well. Like and Subscribe is always appreciated.

I have Pass xa30.8 Wilson Sabrina and a Nagra 300i with some B&w both really nice

What is also really nice is the Devialet amps a mix between A and D class
