Remote Control (Passive) Preamp

I’m in need of a remote control preamp, preferably passive but active could work. I used to have my volume control (passive potentiometer preamp) next to the listening chair and I ran long RCAs to the amps. Now I have all my gear on the other side of the room and have to get up to change the volume. I really liked having the volume next to me so I can fine tune the volume setting based on the track and my listening mood. 

Remote control would be nice. I’ve looked into Khozmo’s stuff and it’s really nice but a pinch out of my price range. Does anyone know of any cheaper solutions or DIY options?

The ideal solution would be a pot-like dial near the listening chair that degrades the signal as little as possible.
