Output impedence for Cary slp98


Does anyone know for sure the output impedence for matching of an amplifier for the cary slp98p. The Cary site states 440 ohms but the manual states 800 ohms. Thanks. Cheers

Stereophile review states 800 Ohms as well... Could one be balanced and the other one unbalanced output?
