D'Agostino vs. Ayre

I don’t want to steal this thread, but I have been thinking about D’Agostino, not compared to Ayre, but compared to Jeff Rowland. I currently have the Jeff Rowland 625 S2 amp and Corus preamp. Has anyone compared them to the Momentum integrated amplifier or does anyone have an opinion on if going from the separate Rowland gear to the integrated would be a lateral move?

Hard to imagine superior sound over Agostino but Rowland certainly going to be awesome as well. I'm not sure that Ayre plays at this level but totally an uninformed opinion. 

The winner, at least for my ears and in my system, has yet to be determined. But the Ayre MX-R Twenties certainly play at the upper level and are competitive with anyone. So far, I have auditioned and declined Krell, Mark Levinson, Pass Labs, and Audio Research amplification.

The description by Khrys is pretty much dead on to what I think.  The Ayre is good, but I prefer the D'Agostino by a large margin.  I prefer a little more flesh on the bone than the Ayre has.  The pride of ownership with Dan's products is off the charts too.

What are the sonic differences between the D'Agostino Momentum S-250 stereo amp and mono 400's? Khrys posted that he preferred the treble of the S-250.
