D’Agostino Progression integrated

This five-figure gear is just audio jewelry in bespoke casework. Amplifiers have been transparent to the source for a few decades now! I bet in a level-matched blind test my Sumo Andromeda would be indistinguishable from any of the above amps.

I’ll take that bet

Only if one is both deaf and a Luddite. 
I bet life is great in a vintage echo chamber. 

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.

I agree about the Pass int. I bought a Rowland Continuum S2 and love it. I have not heard the others.

I listened to int250, progression and Diablo300. With my Watt Puppy 8’s, the Gryphon gave me the most goosebumps; just sounded the most natural, “you’re there”, and the most dynamic ( macro and micro). It was incredibly close with the progression however. The int250 just didn’t do it for me; surprisingly bland and boring.
