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?


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.

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