KEF Speakers

The Heresy's are by no means early offerings by Klipsch. Those are great speakers. I'm a vintage lover myself and love adventure. Just be careful not to spend too much just because it's in great shape. I don't know about you but if it's not a stellar performer, I don't want it no matter what shape it's in. One you simply can't go wrong with is JBL. Vintage or not, they've always been great performers. Klipsch also for that matter. Coral, Yamaha, Pioneer to name a few more. The earliest B&W I would venture would be the DM6, their flagship just before the 801. I've seen them in great shape selling for around $400. I'm not familiar with early Kefs except to say I own a pair of 105 series 2. I believe they were the first computer-aided construction. I bought them new in '79 and loved them for many years however if I had to do it again I would have hunted down a first series pair instead as they were simply better.

Have you tried perusing the KEF Museum? That is a good resource for vintage KEF speakers. Also I've contacted Corey Medley at KEF USA and he has been helpful too. Maybe you can reach out them via website inquiry and they will get back to you. When I needed info for various older KEF speakers Corey was great to work with.

Another great vintage speaker are the Infinity's fwiw.

Thanks guys:) all great info. I ended up buying them, not only was the condition great but they sound great too so I am happy, they compare quite well to my heresys. But I would still like to know more so if anyone learns anything let me know :) thanks

Glad to hear you like 'em! Happy listening :-)
