Man that brings up old memories.
I had more than one of these more years ago than I want to think about. All the speakers I used then are hard to find now. In my memory they had a lot of power but could sound hard. I would stay away from any speaker that might be a little bright already. Older B&Ws or others with a softer treble should work. stan
I used Acoustic Research AR-11's with this model receiver for twenty two years, than I found this web site. Upgraded to Denon AVR-4800 and Energy Veritas V2.2 with Mirage BPS-150i subs.The receiver is back in its box in a closet. The AR-11's are in my bedroom with a Denon PMA-2000 and TU-1500.
