Yessir, I have a pair myself. Mine still retain the original foam grills, which I keep shrinkwrapped for fear of deterioration. It's virtually impossible to find them still intact after 32 years. As long as they haven't been abused sonically and the voice coils are not warped, they should be superior to nearly anything you could buy today. Very high Quality constructed drivers and cabinetry. Crossover is a bit shaky but they get the job done nicely with clean, crisp highs & mids with clear undistorted, tight bass. It really depends on your taste of sound reproduction. The HD 66's appeal to my picky nature and if you knew me, you would know for sure that they are great speakers

I'd get 'em and tease the hell out of someone who bought a pair of $750 speakers as they would sound just as good, hehehe! Have a look at my HD 66's as they are probably the only ones left on the planet still with the original foam grills!
