Klipschorn Floor Speakers, Cheap good Receiver?

[IloveMusicKC]

I am not super informed on what kinda receiver 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. I would like to find a value receiver that I could hook up to them to listen to them a few more times before my mother makes me sell them. Thanks for any help, they are Klipschorn AK-3.
