Tom, as luck would have it, my father bought, and still owns, that EXACT same Sansui component stack from back in the 80's!! It wasn't "ultra" high-end, but it certainly wasn't for cheapskakes either. Every time I go home to Hawaii to visit my folks, I listen to the system and enjoy it thoroughly.
It's just unfortunate that on top of it sits a Bose Lifestyle system... But that's a can of worms I'll leave sealed.
I've never tried the Sansui components with Klipsch speakers, but with the RF-35's (you were considering those, right?) sensitivity, I highly doubt there will be any problem with the Sansui amplifier section driving them. As far as I can tell, the components produce a rich, sweet, and fairly warm sound. I think they would mate quite well with the Reference series.
