Dan D'Agostino S350 vs Luxman M-10X

I've not heard the M-10x, but I have heard Luxman amps and D'Agostinos and to my ear they were a lot more alike than different with Wilsons. 

I mean, one is $45k and the other less than half that. These aren’t really comps.

My bad - thought you were asking about new Momentum Stereo. I wouldn’t go progression at all though. Doesn’t have the magic. 

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.
