There is one speaker from that era which have always had a following the Realistic (Radio Shack) Mach 1. I only know people have sought them from the start and haven't hard any myself. They are still popular but have gotten panned by people used to current audiophile standards, i.e. expecting sound quality equal to or better then todays offerings. I have some old Marantz book shelf from a garage sale I have never used, perhaps I should put them on auction.
