Sorry to "one up" you but, I picked up a pair of HK-40s out of a pile of trash on the curb about two months ago. They are the 10' version. I am using these with a Marantz 2220B, and they sound amazing in my small office. Best computer sound I ever had! BTW, I hooked mine up by plugging a phono plug into the jack on the back, and wiring the plug to a two terminal screw down, and using doubleback tape to stick the screw terminal to the recessed jack panel. Works well, and I didn't mess up the original connectors.
