Dan D'Agostino S350 vs Luxman M-10X

The Luxman is much cheaper ,it’s not as well made ,to the exceptional RR standard but still much better then most. if money is no object the D’A is a work of precision and art .the Luxman is still excellent by any standard, it comes down to $$ .

For the Alexia, between these two, I’d go with the Boulder 1160. Or at least that’s what I have for my Alexia II and it’s a match made in heaven. 

The new Hegel is chopped liver by comparison??

Luxman off course ! D’Agostino is 90% Krell.  À lot of money, and not my cup of tea. I prefer tubes !

Hegel H30A might be a great alternative. I use Hegel 590 with my Sasha DAW, I love the synergy. You can start with one H30A as stereo, you may add another one later to use as mono amp. They are very flexible, excellent reviews as well.
