I wasn't as much into the high end in the late 60's and early 70's as I am now. As a student, I just couldn't afford it.
I didn't become interested in the high end until the mid 80's, well past the golden age. I was mainly intrigued by Maggies and Quads, and I still couldn't afford it. So my "vintage speaker" associations are mainly with JBLs (L88s and 100s), KLHs (17s), ARs (2 and 2As) and various Advents that belonged to friends.
The main difference I hear bewteen speakers 35-40 years ago and speakers in the last 10-15 years is the quality of resolution - "modern" high end speakers, for good or ill, are much more highly resolving than the vintage speakers whether monitors or floorstanders, stats or planars.
(The solid state revolution changed everything.)
I still have some older electronic gear around (Heathkit, Scott, Yamaha, Luxman), much of it loaned to music loving, cash-strapped friends, one of whom I've also loaned my last vintage speakers to. I still enjoy many of older speakers, but I'm not looking to put any vintage speakers in my main system.
In fact, the only "vintage" piece in my main system is a Luxman tuner.
I am surprised, nay *shocked* that anyone considers Apogees vintage. No longer manufactured but of the modern era, surely.
