McIntosh MC1.25KW vs Luxman M-10X

@avanti1960 Magico and Wilson have very different sound characteristics. I can totally see the McIntosh pairing well with the Magico but I doubt these amps are the best you can do for the Wilsons. 
Ideally, if home audition is possible with these different amps, it would settle it once and for all. 
 

Never heard it. Going to make an assumption here but it’ll most likely be out of place in a system you’re putting together. Like I mentioned above, you might want to consider same brand amp and preamp. Get the best possible synergy. Or carefully mix and match. Take it one step at a time. Speakers, then amp, then preamp, considering your source is up to the task. 

Luxman, D’Agostino, Audio Research, Pass Labs XA monoblocks would be nice.
I’ve heard McIntosh sound amazing with some speakers but IMO it just doesn’t have the synergy with the Wilson Audio. Basing this on what I heard in my system. 

@chauncey what preamp will you be using? I’d go for the same brand preamp and amp unless you use dac as preamp. 

Makes sense.
