@OP. The D'Agostino amplifiers have very clean bass - but it is not lean. But it is very far away from the way a lot of tube gear sounds in the bass. The MxV amplifiers are more refined than the Progressions - that's more noticeable from the midrange up.
D’Agostino Integrateds
I am currently running a D’Agostino Progression Integrated after many years of various tube gear and Devialet. Speakers are Rockport Atria. While the resolution and impact are amazing, there is a definite lack of mid-bass warmth. I am wondering if moving up to the MxV Integrated will be the right move, or if I should go in a different direction.
