Threads like this are awesome. I think it needs to be explained why some of us didn't get into Quad. Oh, of course, some will say they didn't want to spend the money, others may say they didn't want all that equipment. Others too young, etc.
I'm 58. So, clearly that puts me on the fringe of not being old enough back when Quad was rolling. Here is the sad thing. I've always been an early adopter and always pushed the boundaries of my listening experience. Even back to the early 70's when I was just a youngster. Had I somehow heard a Quad setup, or even simply heard of it....I would have found a way to get it. I would have saved my allowance, etc. What was holding me back? Clearly, it's a function of where I grew up.
It's clear to me that folks who lived in the larger cities (defined as 100,000 or larger) likely had access to more stereo shops, advertising, more friends who had, etc. If you lived in rural Illinois and were a young teen.....you were totally, 100% sheltered from such things. No internet, no access to larger cities (in rural America 1975, you simply shopped local....never saw a larger city). As a result, Quad was a word I simply never heard. It's as if we lived in a bubble...along with every other rural living person back then.
When I was 12, I had a Kenwood receiver and a turntable and 2 speakers. For whatever reason, I figured out if I steal my parents 2 speakers and wire all 4 together, I could get some sort of expanded stereo. I had all 4 speakers spread out in the corners of my upstairs bedroom. I had NOT heard of Quad, but I knew I liked how this sounded..and well...it just looked cool.
So, it was clear from a young age that I was fascinated with the idea of having more than 2 speakers. Just unfortunate that I didn't have access to the technology or even the understanding that it even existed.
At this stage of my life, I doubt I would ever pursue vintage quad equipment...though it's tempting, believe me. Quad, surround, etc., played through my current equipment give me a hell of a lot of pleasure. Isn't it just great??!!
