In '89 bought the Auricle RD 57 push-pull, planar magnetic, line source, dipole, after seeing the ad in Speakerbuilder. Flew out to audition them and was blown away. For 1085 bucks, a pair delivered to Framingham MA. The best deal in audio. Dave Graebener hit a grand slam on this transducer.
@@theaterdesignco Thanks, but my RD 57 still works amazingly well being powered by 25 Watt tube OTL monoblocs kits from Transcendent Sound. The company Radia manufactures in the US, the BG line, too. As do the chinese. But Wisdom is crazy expensive,.

Take a look at Wisdom audio. A lot of there speakers have Graebener design.
