KEF Speakers

You probably don't want ancient Kefs or B&Ws as they would be their early/first offerings. The examples they themselves learned from.

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.

Another great vintage speaker are the Infinity's fwiw.
