Advice? Luxman C-900u vs. Pass XP22 vs. Ayre kx5-twenty

I am thinking of upgrading my Hegel P-20 pre but cannot find any place to audition. Here are my choices:

Luxman C-900 U and Pass XP-22, about the same price used, very similar conditions (<3 years old, excellent condition).

Ayre Kx5-20 is about $65% of the Luxman or Pass used.

Which one presends more value, sound, and match to my system?

System:

Pass XA100.5 Monos, Martin Logan Summit X speaker, PS Audio Directstream DAC...

Thanks in advnace.
