Planning a vintage setup

Wow time flies, I would never have considered Ayre vintage but looking them up they have been around 25 years now wow. 

KEF made a big splash when new, excellent finish and sound great, but I advise against them because of low sensitivity and too deep for ..... 

I always want efficient enough to more readily try tubes, now or future.

Turns out none of the Proceed Amp 2s is functional, and after soul-searching I doubt I really want to sell the modern Ayre gear. I envision a simple setup of DAC, preamp, and amp with KEF Reference 1s, maybe subs but no surround. A Sony HT A9 SW5 does surround. This ends my plan for a vintage setup unless I bring up the Ayre AX-7e and C5xe with appropriate speakers, e.g., KEF Reference 102/2s.

I tried the Ayre AX-7e integrated with KEF Reference 1s, and the sound was excellent, but those speakers will be used with modern Ayre gear.  I may try it with a Magnapan LRS.   Any suggestions about vintage speakers?

The Ayre AX-7e integrated and C5xeMP disc player sound so good with the KEF Reference 1s I may forego setting up the modern Ayre gear.  I have a vintage Ayre DAC that could take USB from the Roon Nucleus and send balanced analog to the AX-7e.  

An Oppo 205 can be linked via HDMI to a Sony HT A9 surround setup to supplement the vintage setup.  Our primary setup is a KEF LS60 with a pair of KC62 subs.
