I may be wrong, but I do believe that the style of audio featured in this advertisement is never going to be collectable. Despite the futuristic aesthetics, the brute power, and the funky lights, hifi hunters have passed this era by! Instead, the next wave of classic audio gear that is starting to rise in price is the mid- to late-eighties upper end equipment. In other words, this early ’80s stuff has been completely disregarded. One seldom sees these receivers for sale — did they sell in small quantities or did they break down and get tossed in the garbage? I wouldn’t be surprised if it was the latter as Technics (and many others) around this time put chips into their equipment that made them essentially unfixable if they failed.
One of the reasons why Technics outsold Pioneer by 4 to 1 in the 1980s. While Pioneer wandered off into strange plastic, computer-age gear, Technics stuck to the basics in terms of styling as well as offering more than most in terms of power. Also note how the Technics ads from this era are much more visually appealing that the dry, colorless Pioneer fare:
