Remembering the first demonstration of LS3/5a speakers given to me in 1977 or 1978. Most probably Rogers. Quite fine, not great; driven by a huge Audio Research tube amplifier. Not forgotten...so must have impressed.
Then in 1978 I purchased a pair of JR-149s...my main speakers for perhaps three years...mostly driven by a GAS Son of Ampzilla and later by a Marantz 8B. This was such a fine speaker for the kinds of music I was listening to back then...mostly acoustic instrumental...jazz, bluegrass, classical recital, etc. Imaging to die for, scaled beautifully, much better bottom than the LS3/5a. They did suffer a peaky nasal quality that compromised voice. (About 5 years ago I picked up a pair second hand for about 30 days -- all the glories and limitations remained - then quickly sold, that midrange was no longer acceptable
.)
Spendor 15 ohm LS3/5a found their way into my household in 1982. Remained a fixture in 1st and 2nd systems well over 20 years. That's quite a long run for this audiofool.
Reviews of Spendor 3/5s were so over the top ten years ago that I was persuaded to give them a try. It took about a minute to conclude they were a far superior monitor to the LS3/5a. Real technical advances over 25 years.
Finally, about 18 months ago I took a flier on the newer Spendor 3/5R -- and these were better still. Greater dynamics; better balance and tone; and it scales so beautifully in the right sized room -- a
most impressive audio magic trick. I love 'em...a ridiculous affection.
In addition I've short listened to the comparable shoe box sized Harbeths -- also just extraordinary in their presentation. And I assume there must be a half dozen other little monitors that have their champions.
So the vintage speakers are fun ... a little like looking at pictures of old girlfriends (or wives...).
By analogy the current units are the most refined trophy wives...minus the terrible expense, of course!
