I have the sonographe SA-250 and its a good amp with a clean, warm sound. Mini-review in Stereophile May 2000, Stereophile class B recommended amp in 2001. The SA-400 should sound the same if not better.
CJ Sonographe SA-400 now discontinued Any good?
Conrad-Johnson Amps in general seem to be highly regarded. But I have seen this amp (brand new) selling for nearly half its retail price of $1700 with little or no interest. Is this amp an undiscovered gem or a black sheep in the CJ family. What would you recommend for a solid state amp in the $2000 dollar range to drive a pair of Paradigm Studio 60's?
