jbl paragon  

JBL D44000 is the first stereo speaker system designed for home use back in 1957, about 1000 built altogether (production ceased in 1983). A privileged few still have one. 

Well, one excellent specimen is in my office-room throughout 2023 and 2024.

You are welcome to come visit, listen to some music, and talk about HIFI. Or about business-class. And intercontinental flights. We did spend a full hour with Dr. Milen Vrabevski (INTELLIGENT MUSIC PROJECT) recently.
