Sorry for the repeat post.
billybob, I really appreciate your input. That’s exactly what I needed for a starting point. Looking at eBay the Heresy’s are all over the place. Many are around $1500, but you can’t go by what someone is asking, only by sales, of course.
marvel, I noticed the date on the round terminals of my HIIs is 1985. My records say I paid for them in Oct 1986, so who knows? I do know I’ve had some almost surreal moments listening to them over the years. All kinds of music. The stereo shop put Sade Smooth Operator on when I listened to them and I’d never heard speakers sound so good. Of course, he probably had them wired to $4000 amps in the shop! My friends all loved them and we had some good times together. As I’m sure you probably have with yours. Enjoy!
