Classic speakers to hunt down used

It's a flashback to 1971 for me, but for what it's worth, here's a coredump of my memory when I was a teenager...

Dynaco A25--way more integrated and driverless sound than AR, Advent, (and just plain boring KLHs)and simply ahead of its time. I used them with great joy for 5-10 years back then. Even Dynaco itself never bettered it (with later A35s and A50s, which I tried and then got rid of). The A25s had such a unified, natural sound they were miraculous for the price.

OK, I admit I did like the KLH 17.

For what it's worth, I also liked the HH Scott S15 (very hard to find, but if you see a pair and you want classic speakers, grab it).

I don't know why everyone liked Advents so much. I owned a pair and thought the tweeter was tizzy and never blended into the soundfield.

The ARs I liked were the 3A, the 6, and the 4x, but the Dynacos was superior all of them. (I used to listen to them at the AR room in Grand Central Station.)

OK, back to the future now...

how old does the speaker have to be to be considered "classic?"

I would say all of the original Infinity Kappa series.

Mitch:

Accepting that there is a distinction between classic and vintage, you're talking at least 25 years to be considered vintage.

For audio I would say the vintage eras are:

hifi components: primarily made in USA (up to 1968); first Japanese wave (1968 to mid 1970's); second Japanese wave (mid to late 1970's); everything else

speakers:

60's; 70's; everything else
