I like D'Agostino amps a lot. Not sure I like them 10x more than Luxmans but I do.
What I've heard so far:
D'Agostino > Luxman > Pass
Sorry I haven't heard the others listed, but if Luxman is a possible audition you should try it.
D’Agostino Progression integrated
What are your thoughts on the Progression int? How does it compare to integrated amps like Gryphon Diablo 300, Vitus 101 mkII and and Pass int250?
