Thanks for the welcome! I have and Adcom 5400 that powers my AR-3a's, I want to hook it up to the KG-4s to see what more power can do for them.
As for the sensitivity rating, are you suggesting that the earlier versions Max2 and I have are actually 94db but misbadged? I've read about the 4ohm / 6 ohm stuff being marketing ploy in the mid 80's. But nothing on the variance of sensitivity of these early KG-4s
