Perhaps you can sell your non-remote Audio Research pre and replace it with a remote Audio Research pre?
Remote volume control for preamp?
I would like to remotely control the volume on a favorite preamp of mine(Audio research). Is there a fairly inexpensive device that can hook up to a preamp so you can use a remote control to adjust the volume? It's seems to me, that this would be a very in demand item, and so they must exist.
