I am not super informed on what kinda receiver and or amp I need to run these speakers. My dad used to play them when I was younger and all my friends would go crazy they couldn't believe how loud they are. I haven't heard them in years but they have been sitting in the same basement. Problem is my mother got rid of the receiver/amp. I would like to find a low price(under 300 if even possible) receiver/amp that I could hook up to them to listen to them a few more times, my brothers and mom kinda want me to try and sell them but I want to hear them again first I remember being in shock listening to how cool they sounded but its been about 20 plus years. Thanks for any help, they are Klipschorn AK-3.
