Hi Swampwalker; The McCormack amps-- all of them sound great with Vandersteen 2Ces, 3As, and 3Asigs.. I would guess that's true for the earlier 2Cis as well. Richard Vandersteen and Steve McCormack used to exhibit together and use each others products. I haven't heard the new 125 & 225 amps, but own the DNA-2DX and DNA.5, along with Vand. 3Asigs., and 2Ces. They're great together. Good Luck. Craig.
