Having read the product description of the new version 3 Dodd mono amps, I'll have to retract my unqualified recommendation of versions 1 and 2 for use with the Sonata III, which are presently for sale. The reasons are that the new version 3 boasts a better power supply, more headroom and quieter operation. With your high sensitivity loudspeakers quiet is important, and the mention of the quietness of the version 3 makes me suspect of the quietness of the versions 1 and 2 paired with the Sonata III. You'd have to hear them to be certain. If they worked, they'd be great bargains though.
FYI, version 1 sold to many Audiocircle members for $2500/pair new (and everyone was creaming their jeans about how good they were). IMO, that puts the value of used version 1 amps somewhere below $2000...maybe even lower? Perhaps a great value in a tube amp, but they don't have a large pool of interested buyers and therefore resale suffers.
