This came out of nowhere. My friend gave me his floorstanding speakers (Klipsch RF-3 II) and I'm not an audiophile and don't even own a receiver. Of course, I think it needs an amplifier or receiver or that sort of audio equipment. The problem is that I'm on a very tight budget. Can someone familiar with old school audio equipment help me out with this? I think these are pretty good and I'd hate to not be able to use it. I'm connecting it to my iMac as external speakers so I won't need gazillion inputs. Just something that can play the sounds of my iMac.
