I have no doubt this has been covered countless times here, so I ask for forgiveness. What do I need to look out for, in a search for OLA's? I'm an oldtimer, who sold many Advents in a store in western Mass, decades ago. I had a pair of OLA's, at the time. I had traded in AR3a's for them, because they sounded better. Then I traded them for powered Advents, which went in a burglary. I now have hankering for a pair of OLA's. I have no problem if I need to refoam them. I've been searching ebay, and find prices from sellers with excellent feedback, are surprisingly low. Someone, 2 hours away, 1100 transactiions, 100% feedback, will take $250 for a pair, locally, after auditioning.
