It was in New Orleans. Ranked in sales - Heresy, K Horn, LaScala, Cornwall, Belle. Actually sold three pairs of K Horns to three different people in lees than two hours! The store owner was there and was amazed. Good products are are easier to sell!
We also did Disco installs and restaurants. We did a club with double K Horn bottoms and a single K Horn mid / tweeter top section.
Most of the installs were Heresy's hung upside down near the ceilings.
In that era Crown - DC300A, ESL-224 electrostatic, C8 speakers, Phase Linear 700, 700B, 400, RTR, Citation 11 & 12 (assembled and in kit form), Dynamo PAS3 & Stereo 70,Dahlquist DQ-10, QUAD ESL (there was a frame available to stack Quad's), JBL Century 100 & Paragon, Levinson had just introduced the JC-1 preamp, Yamaha rolled out their initial receiver series, and the large utility / deluxe Advent's were hot (double advents - stacked tweeter to tweeter). And even Bose 901's, double 901's and Bose had their own amp & preamp - looked good - sounded like ....
We took on Audio Research (D-51, D-75, D76A, SP-3A0 and the Magnapn Tympani 1A (four bass panels and two tweeter / mid panels). Since the speaker was so large, it was a difficult sale - I sold only one set.
We also did the Advent TV - convergence nightmare!!
The Dahlquist rep that came by at that time as a guest for one of my open houses was non other than Saul Marantz ) I was surprised)! We had an interesting discussion about the Quad ESL 57 (met Peter and Ross Walker at CES in Chicago) versus the Dahlquist DQ-10. I still have his autograph.
I knew Davey O'Brien from McIntosh and would take components to the McIntosh clinic at another audio store when they were in town. very nice man.
