D’Agostino Progression integrated vs Gryphon Diablo 300

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".

@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.?

@pfrank12 I'd bet that a high percentage of those who have owned either amp have arrived at similar conclusions.

I'm not suggesting that there aren't differences, but the vast majority of audiophiles would likely be very happy to own either one.
