Pass XP10, Ayre K-5xe, Calypso - Your Experience?

Hi, I acquired a pair of Harbeth C7ES-3 and am now putting together a system for these speakers.

Anyone has experience with the Pass XP10, Ayre K-5xe, Aesthetix Calypso, ARC LS-17 & 26, CJ ET-2 or ET-3? I know they're not in the same price range new or used.

For the Pass XP10, I might consider the XA 30.5 or X150.5.
As to Arye K-5xe, I'm looking at Ayre V-5xe.

For ARC LS 71 or 26, will they work with Pass XA 30.5 or X150.5 as far as output/input impedence is concerned? Any decent SS amp (at $2-3K) that works well with ARC pre-amp?

There're so many ARC power amp models (old ones). I have no idea which ones are good. Any recommendations? Same case for the CJ.

I don't have any chance auditioning these pre-amps yet. There's no Pass dealer in my living area.

Thank you.
