old pioneer/sansui recievers values

[SIRDRINKSALLOT]

I must admit that I joined this site to obtain info on a full size expotential horn for my clarion SRW8000(yes that's the 32" driver and yes I do have an empty room that measures 16X22 that I'm willing to use to keep it in. However, I need help on some vintage audio values. I want to know receiver values because I recently traded drywall work for audio equipment. The first item is a Pioneer SX-D7000 and the other receiver is a Sansui G701. Just wondering if anybody is looking for these or knows the value of them. They look beautifull, but with a Yamaha M-60 and a QSC model 41 I don't need these items. Thank you.
