D’Agostino Progression integrated vs Gryphon Diablo 300

@ebm 

First, your claim would be far more compelling if it included some details. In what way(s) do you believe that the D’Agostino is better made? Secondly, under what conditions have you heard both? Did you really AB them, or did you hear them with different associated components, etc.?

Don’t know what Diablo you were looking as that Diablo name goes way back with Gryphon?

I’ve seen the Diablo 300 but not the D’Agostino, but what I can say is the build quality of the Diablo 300 is beautiful to look at if you like that kind styling which I do, very solid and fit and finish is like a Swiss watch.

Heard Dans amp with Magico A3s and Esoteric cd player.Heard Gryphon at few stereo shows.Dans amp had better bass detail,bass impact and better delineated midrange and highs.

Ludicrous. You can't accurately compare the two using different associated components, (presumably) music, and in different rooms.

And we're still awaiting your insights into how the D’Agostino is "better made".

Ludicrous  i thought he was a rapper.Keep waiting.Dans unit has a much better transformer,wiring and better cap just to name a few.Are you buying them soon?
