Aside from experiences in studios, as teenager in the 1970s my exposure to "High End" kit came almost exclusively from often seriously dodgy bars dotted around Europe where the fug of slightly acrid cannabis smoke was a dead give away. Often tucked away in some street even the pickpockets were loathe to venture into in case they might be "infected" , I had some, verging on spiritual experiences, under the influence of "Afghani Black" , which was slightly harder than anthracite and looked remarkably similar. listening to some of those systems. The fully pro EMT turntable in the cupboard of a tiny bar in the Juliana district of Copenhagen driving a walloping great pair of JBL studio monitors via a pair of grey import Pioneer power amps, was a religious experience.
My experience was that, the Venn Diagram of stoners and Hi-fi nuts was, for me, a almost a single circle. There was a definite "culture" clash between my generation and the "Rivet counters" who had grown up in the 50s and early 60s and seemed to be mostly, into jazz, if not the incumbent "cigarettes" that it came with as part of its baggage. Funnily enough, decades later, it's still the "stoner mates" who who buy still buy Hi=fi and everyone of us have infected ..cough cough, our offspring with the "hobby" by a form of osmosis. Several of my friends have upgraded their vinyl systems as result of their offspring taking "That old Turntable of yours" to college with them.
As such, I feel I belong to an entire generation who are treated as "invisible" and yet, without us. I strongly suspect several brands would have vanished as the multi-media world took over from the days of "TV, Film, Albums/Radio and Books hegemony". Without wishing to make this political, those bars, that launched a thousand lusts for better kit, were driven out by the corporatisation of Europe. What was once "essentially sleaze and yet safe" has become an anodyne facsimile of those experiences where today's "Yoof" are told "They are having a wonderful time...sponsored by", not making their minds up for themselves and the music they are exposed to is likewise, almost wholly corporately sponsored.
There lies the conundrum at the heart of anything that involves art, the movers and shakers are nearly always "outsiders from the fringe" and yet, at some point, everyone has to gird up their loins and talk turkey about business and making some sort of "career". Most improvement in Hi-fi were achieved, not because there was some fiscal end game, rather, it was just someone, somewhere, thinking, "You can improve on that surely?".
If you want an example of someone who is a "good person", the dude who owns both the Access synth and Kemper amp modelling brands. They invented the downloadable firmware upgrade and my 10 year old Kemper receives free updates for life. I have a feeling he and dear old Ivor would not "get on"...
