I sold mine for $200 last year. It's` a better stereo pre than Pro-Logic piece. The P-L processor is very noisey by today's standards. The programable remote is seriously short on memory too. I reprogramed it so many times and always ran out of memory before I could enable all the buttons I wanted. Despite all that I really liked it back in the early 90's when I got it. It was the first time I got to use the digital output of a Laserdisc player. I never really mastered all the equalizer functions. It was a bit much. It's one of most complex components I've ever seen. Oh, the DSP functions were pretty much useless. None of them sounded good. I only used stereo and Pro-Logic. I had a hard time selling mine. I finally sold it to a musican who had no intrest in surroud sound. Best wishes!
It's probably worth $100-200. I've got one that I bought new, what, a decade ago, and I just packed it away in a box, 'cause I can't bear to sell it for a 1/12 of what I paid. I'd have to disagree with Rachael, and say that I was never impressed with it as a stereo preamp. In fact I stopped using it for that many years ago, only pulling it into service for prologic use. As it is a digital preamp with no way to bypass all those old chips, (unlike it's successor the 2000ESD), it's pretty worthless for much of anything. If I could figure out how to wire an analog bypass, it might make an OK switcher for some non-critical applications.
