I’m always slightly wary of recorded comparisons. They’re good for telling the general differences between two or more speakers, but at the end of the day you’ll be listening to million dollar speakers, as heard by a mic costing a fraction of that, encoded by YouTube, and then reproduced on your speakers that are probably 1/1000th the cost.
Another issue, although I may well be wrong here, is that the super boutique high end market really didn’t exist in the same form that it does now, did it? When I think ultra expensive vintage, I think of the Klipshorn, the EV Patrician, the Pioneer HPM1500, Magnepans, McIntosh anything, or that JBL that looks like a MCM coffee table. Today’s plutocrats are a bit more spoiled for choice!
That being said, as a college student, I’m in a price bracket where I can get good quality vintage or so-so modern gear. If I had the dough and the space, a set of Khorns or MartinLogan electrostats would relegate vintage anything to my B switch, if not Craigslist. But would I have the same satisfaction of running across some hitherto unknown (to me, anyway) gems for a steal, cleaning the cabinets, repairing the crossovers, and own something that’s increasingly disappearing from the modern world? To have the grin-worthy joy of hearing classic designs pound out modern music with the slightest ease? To me, that’s a decent part of the fun here.
