SAE: Whatever happened to them?

I remember in the seventies walking into a Cal Stereo store in the LA area and seeing the SAE equipment. I was a college student back then and owned a reciever. The SAE stuff with it's black metal and white graphics looked sooo imposing and impressive. Amp, preamp, tuner and EQ all in one, if I could ever own something like that one day! By the time I could afford decent equipment, SAE has been long gone.

Was their stuff any good?

What happened to them?
