Ortofon was a name to recon with and in some ways and I preferred Empire turntables, but owned Thorens because I could easily change arms, which I did quite a lot. If you liked Horn Speakers Klipsch was still a force back then. JBL, Altec, EV, Frazier, Tannoy were continually updating their products. Mcintosh was building the MC 3500, one of the best tube amps ever built, that easily reached 440 watts. Mac started introducing the 2000 series SS amps and their ML series speakers. Straight line tracking turntables were just around the corner. marantz 7T pre-amp and series of SS amps were great sounding units. JBL came out with newer ring radiators, the orginals were horrid. EV was trying to upgrade their consummer sales with the Interface models and the Bose was starting to introduce the 901. You either loved them or hated them.
Some where in there Panel speakers and the KLH 9 grabbed everyones attention. Japanese where entering the market in a big way and the power wars were just around the corner. As others have said Nakamichi was making waves and so was Stax Earspeakers. Koss was making their electrostatic head phone, ESP 9. Tandberg with its bias head was a real leader in performance if not in long lasting duration. Ampex had introduced the AG series SS professional recorders and the Nuvistor MR-70 was being phased out. The most important happening was the advent of high out put audio tape started by the cassette recorder scene that made R2R machines with built in reserve capable of a magnitude of increase performance. Increasing signal- to- noise, reducing distortion, and reducing tape saturation at lower speeds. Dolby came along with a noise reduction system that helped FM broadcasts and helped improve audio tapes. DBX was new with its much anticipated systems. Sheffield was introducing DIrect-to-Disck LP's. Original Masters was introducing Soundstream digital to analog LP's. Quad, 4-channel was coming, as was the disco craze!
