D’Agostino Progression integrated vs Gryphon Diablo 300

have not heard the Gryphon, but I heard the Momentum and then was able to find one used. It ended my search for the sound I was looking for. "mike drop".

@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. 

whipsaw; that's a high percentage bet and I agree, but it is influenced by your personal preferences and biases regarding the sound you are looking for.

Not going to bore everyone. That being said I heard both. Separate places so n AB comparison. They sounded as you would expect -really good . Both with Wilson Sabrinas. The only thing I can comment on is that you need to listen to separates before you take the plunge $$$$$. Maybe it’s in my head but I would rather go for more Dollars (Preamp- Amp)  

Separates. What can you get for $16k-$18k new including interconnects and extra power cord ? Probably much more dollars to beat those integrateds. With $45k D'Agostino Momentum integrated, that's different.
