I am running these amps along with the linestage and the sound is the best I've had (or frankly ever heard). Hard to pick an area of special merit because they just sound more musical and utterlt envolving so the details are less on my mind. They have replaced an FM Acoustics amp of twice the cost and before that Goldmund electronics that were in the $50 K range and there is just NO comparison thse are a breakthrough product.
Interestingly the comments pertain to the amps run in conventional fashion- ther is a free upgrade that I stumbled upon that raises the sonic level to a degree and in a way I would have thought impossible in and audio system- all areas are vastly improves by this uprade but the addition of a preaiously unavailable FLOW of the notes combined with graeter detail AND greater organicity. So as to avoid soundindg completely daft let me explain that omost componenets inside the amp are on a metal supprt that attatches to the SIDES of the unit while nothing touches the bottom plate. When placed conventionaly and feet are under the bottom plate no great amount of energy is drained from the internal components but when placed on it's end and grounded by footers the mechanical energy has a route away from the internal components and the sound is HUGELY improved upon- in fact the increment is even greATER THAN that envolved in changing to this fine amps in the first place.
