John Iverson of Electron Kinetics and Electro Research? His speaker might have been something to fear!

Here Harry Pearson talks about Iverson.

Electro Research A-75
This unit was designed by John Iverson, one of the high-end's most memorable characters, around whom many a story, even legend hath sprung up. The solid-state A-75 was built for the military, perhaps for a radar installation. It was thus built to military specs (and overbuilt for audio listening purposes). So, it was said only a few units were left over for Iverson to sell to the general public. When they worked without breaking down, they were unlike, in sound, anything else on the market. The thing I remember best about them was their incredible purity, both at the tightly defined and taut bass frequencies on up into the, like their designer, ethereal ionospheric regions. Iverson was also legendary for developing a "force-field" speaker that, it is said, the military had its evil eye upon for some dark purposes. (Legend: It could make solid-objects disappear into a nowhere dimension.) There were other designs that did not quite materialize either, including a strain-gauge cartridge/preamp. No one, to my knowledge, ever heard one of those gizmodos. Later on, Iverson simply disappeared, after one or more runs in with the law, or, perhaps, to his alternate business base in Singapore. Many have tried to find him but no one has, so complete is the mystery. (Legend: He was assassinated. Maybe not. Maybe he simply fed himself into his force-field speaker.)
