Sorry to say but there is nothing vintage on that Youtube channel. I wouldn't even say it was classic equipment, although the A60 and Naim Nait will be edging towards the classic side in a few years time...
Vintage is pre 1950s
Classic is pre 1970s
Vintage is pre 1950s
Classic is pre 1970s
I don’t agree with that at all. To my mind anything that is highly desirable, sought after and collectable 20-30 or more years later is ‘classic audio’, e.g. I’d certainly put a lot of stuff from the ‘70s and ‘80s in there. I view it as a market-defined term, and if something is worth serious money 30+ years later, likely far more than it cost new, then it can’t not be in that category!
Unless you were born in the 80's like me, where pre 1950s is antique, vintage is pre 1980s, classic is pre-2000s.
How can vintage be pre 1980s when 99.99% of electronics was transistor based back then. The transistor is modern technology so it can't be vintage. Vintage is valve or tube based and would be pre 1950s...
I used to deal in the vintage and classic market in the 1990s/2000s as I used to restore a lot of that equipment. Back then no one wanted anything with transistors in. It was pretty much worthless and you couldn't even give the stuff away, like Leak Stereo 30 and 70 amplifiers...
Trouble is that most audio equipment post 70s and 80s isn't highly desirable. A good guide is to see what audio equipment prices go for in Japan. If equipment isn't listed there, then it isn't desirable.
The market has changed hugely since then. The better 1970s Marantz, Pioneer, Sony, Sansui, Luxman, Kenwood, McIntosh etc kit is now all very desirable (it never stopped being so in America and much of the world), as is Sugden, Quad, Naim, Exposure etc solid state. Same goes for TD-150s, TD-125s, LP12s, countless of the better Japanese direct drives, LS3/5As and other BBC monitors, Gale 401s, countless Tannoys, JBLs, Magnapans etc. The Leak Stereo 30, 70 etc are good indicators that the market knows what it is doing, they weren’t rated at the time either! Time always sorts things out.
The main reason the market has changed and a lot of the brands you mention have become popular now is due to the unavailability of the older more desirable stuff and the high prices they fetch if they ever do become available.
