looking for older Infinity speakers

Where are quantum speakers comparing to Kappas? What age are you looking for?

Are the quantums around the late 70's ?

I thought they sounded familiar. I was drooling over those infinity speakers while stationed in Germany back in the mid to late 70's. My wife and I ended up settling on a pair of Bose 901's. What a compromise that was... couldn't afford the infinity's on an E-3's monthly salary, in those sparse years. I have recently upgraded to a pair of Legacy Focus and in the process of selling a pair of original Kappa 8's. Would like to find a buyer for these.
