That's fascinating--thanks for that! (This link will get you
directly to the article, b/t/w.) If it hasn't been done already, we should start an index page somewhere with links to articles like this. Somebody could put together a very cool anthology...
Most of this quad history is still new to me, so I didn't know that David Hafler was one of the early figures in bringing quad to the masses. (I see now that there's lots on the web about his system, including
a year-old thread here on QQ that I missed.) I only knew him as the father of Dynaco, though by the time I was old enough to take an interest in hi-fi, he'd left and founded his namesake company. I built one of
his first pre-amps, to pair with a
Carver cube amp that I'd saved two years' worth of summer-job wages for. A few years later my apartment was burgled and I lost both pieces. Then just last year, decades later and on the other side of the country, I found the same unit--probably constructed a little more professionally than mine had been!--in a junk electronics store. Paid forty bucks for it, got it working, and now it serves as my turntable pre-amp.
