D'Agostino Progression monoblocks replacing my Theta Prometheus monoblocks

Nailed it!

George, After changing from the Theta Prometheus (which is a really great sounding amp) I have had a pair of ARC Ref 250 SE monoblocks, and Momentum monos for a back to back comparison. All three were with the same ARC Ref 10 preamp.

I am very happy with the D'Agostino Progression monoblocks. I am not the first to mention how dynamic these amps are. This was evident listening to the CD Red Violin. Track 20 has some very loud orchestral peaks on the track. It was amazing to hear these amps reproduce effortlessly the dynamics on it. It was loud but yet I was able to hear every instrument clearly for the very first time. My ears will give out before reaching the full potential! It is the headroom you notice. I have noticed also that these amplifiers are very revealing of poor recordings. The ARC Ref 250 SE monoblocks I had on loan made the normally "poor sounding" discs listenable because of the tubes in my Ref 10 and the tubes in the amps. This is not necessarily right but expected with an all tube system. With the Progression monoblocks my well known recorded redbook discs sound fantastic with small little details not heard before in the recordings being heard now! With SACD listening to them now is definitely better and confirming the reason for having them to begin with! Listening to both male and female vocals they are smooth and natural with a touch of air on both. The better the recording the more is revealed. I am waiting for both of my Transparent power cords to be reterminated to 20A.
