D’Agostino Progression integrated vs Gryphon Diablo 300

Dans amp is better made sounds much better and is made in USA.

you have heard the two amps in a proper comparo, @ebm ??

@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.
