Amp advise :)

Hi there! I have a question and I would love to know your opinion. Currently my equipment has
Esoteric XD digital source,
Technics turntable analog source (Luxman eq-500 preamp)
Integrated 2A3 tube amp,
Klipsch speakers.

My intention is go to separates. Only reading forums and reviews I found interesting:
Preamp:
Luxman c-900
Nagra classic
Arc ref s6se
Robert Koda k-10 (used)

Amp:
Nagra Amp.
Arc 80s
Gryphon Essence

The budget for a couple of these would be between 30/40.

Does anyone have experience of good synergies of preamp/amp between Esoteric source and horns?

thanks a lot, be safe :)
