In that college town we also had a very high end stereo store, and I remember in one of the magazines they sold in there, I read a story about some guy that had a problem with the design of some amplifier. It was a review magazine, and they were very thorough. They sent square wave through the amp, and these guys redesigned the amp and changed a lot of the design parameters and produced a better amp and then the company began selling that amp with a letter designation after the model. It was really high end like $1000. single channel, you had to buy 2 for stereo. But that story was one of the things that got us on the tv circuit thing. and although to the naked ear you could not tell the difference between the original and the redesigned amp, the difference was all math, and what the O'scope showed. Funny thing was a lot of low end amps sounded really good on higher end speakers. Same is true for the tv's the display tube did make all the difference, one thing we did not get into, so maybe Zenith had a better output device, and designed accordingly.
