D'Agostino vs. Ayre


To anyone who has heard the D'Agostino Momentum series amps and the latest Ayre MX-R Twenty, care to compare and contrast the sound?

Great great choices of amps for your Alexias. You can hardly go wrong. I stand by my assertion that high powered tubes like VTL  Siegfrieds are preferable with Alexias. The S-400s are adequate but insufficient. The S-250 will outperform anything but expensive high powered glass with your speakers IMHO. 






FWIW I have an S-250 driving a new pair of Wilson Yvettes. Nirvana over at my house. 

High powered tubes are a long shot, for me. I can't afford a pair of Seigfrieds. I've tried to work a deal to purchase a used S-400, but just learned yesterday that the cost to upgrade one to Series II status is $20K.  And from what khrys says, the S-400 might be inadequate. So it will most likely be solid state in my system. The D'Agostino or the Ayres.
Enjoy your S-250. It takes little break in to reveal its prodigious capabilities.

Wilson Alexia’s give a EPDR load as seen by the amp, of an incredible low 0.9ohm in the bass, you really need D’Agostino type current pushing amps for this type of load, if you want to get the very best from the Alexia bass.
