The Vivas are more musical, fleshed-out and more life-like (particulary with voices and midband instruments) than the Lamm/MR combo I had.
With just 28 watts per channel it drives my Giarneris very well, no hint of clipping or saturation, they lack the linearity and both extremes resolution of the later, but the reproduction of most material (particulary Jazz and Ensambles) is captivating.
I understand that the pre/power combination from Viva is even more dynamic and textured, as well as the inclusion of the Fono preamp from them which just received great acolades from the press.
Happily parked here for now :)
