The only thing Carver did was to add a low value resistor in series with the output of the solid state amp. A one ohm resistor brings the damping factor of his amp down to the level of a typical tube amp output impedance. I think long term listening would have disclosed differences that an a/b comparison sometimes obscures.
He did the same thing on one of the outputs of his Sunfire amp.
Follow Ups:
The resistor would only increase the output impedance of the amp which would make it interact with a speaker like a low damping factor amp like a tube amp. But Carver made his amp sound just like the reference amp. And I confirmed the Stereophile article directly with Gordon Holt. So I suspect there was more than just a resistor added.
But Carver does add a series resistor option in some of his amps . The current outputs on the Sunfire a good example.
Apparently Carver noodled away for a day or longer, 'nulling' the amps against one another which implied they sounded the same to probably 70db down.
Much more than a simple resistor added to the outputs.
Too much is never enough
