PS Audio BHK 300 mono VS Modwright KWA 150SE mono VS D'agostino Classic stereo

scar972 very good description of the D'agostino Classic amp thanks very much, it will serve everyone considering this amp.
So with this amp it is wise to consider a good tube preamp like VAC or VTL.

I have no doubt the  D'agostino Classic Stereo Amp sounds excellent.  The Ken Kessler hi-fi news review compares the sound of the Classic Stereo favorably to (or, in the ballpark of) D'agostino's Momentum amp.

I observed the lab report in the hi-fi news review indicated the amp does not double power from 8 to 4 to 2 ohms.  There is plenty of power, no doubt, but it seems they may have played with the power specs a bit, i.e., underplaying the 8 ohm power to indicate a doubling into 4 ohms but, in fact, the results indicate the output is less than 600 wpc into 4 ohms, or about 150% of the output into 8 ohms.

The other thing I was curious about in looking at the pictures of the insides of the amp, was the absence of either big capacitors or lots of medium-sized capacitors.  There are four 6800uf storage caps mounted on each channel's board, and some smaller caps, but there appear to be like 16 output devices per channel so I am surprised there is not more capacitance provided.  It is possible there are other caps that I cannot see in the picture but it looks like there is a lot of empty space between the two boards and the associated heat sinks they are mounted to.

I guess I am used to the two huge (think 24oz Colt 45 tall-boy) capacitors in each of my Clayton monos (but that may not be a fair comparison since the Claytons are biased in Class A) or the 14 or so medium sized caps per side in my David Reich designed McCormack DNA-2 LAE.  Both of those amps are also rated at 300/600 wpc.

There is a dealer located near a city I travel to for work so if I get to hear the D'agostino Classic Stereo Amp I will report back.  If I were looking for similar power, it would be on my list to look at.

Good observations mitch2, let us know when you can make an audition.
I wonder how the D'agostino classic would do against the Karan KAS 600.

By the way i have decided that i will purchase a pair of Thiel CS 7.2 as soon as i find a pair for sale.
Therefore i have to take this into consideration for my amp selection.
Need an amp that will drive both 3.7s and 7.2s with ease and refinement.
The D'agostino classic amp would be a good starting point for some years until i can upgrade to the Momentum monoblocks.
If by any chance the Ypsilons can handle both of these speakers i would rather go the Ypsilon route.

Thieliste,  not sure you want to hear this,  however,  each time I pull up Thiel 3.7 or 7.2 on YouTube,  nearly every video there was krell on these speaker's,  I mind you,  they sounded damn good to me,  I understand opinions are just that,  an opinion,  I believe you will have a smile for a long time after extensive break-in of the Dan D’Agostino classic stereo amplifier,  btw,  Dan himself helped me with my amplifier, I have the only modified krell 700cx out there,  this was completed December 2014, hugely better than a stock 700cx,  so yes,  I'm a Dan D’Agostino and Nelson pass fan, cheers.
