I think you mean more of a remote display than a detachable face.

The detachable face idea will cause problems with RF emissions from the player unit if it is operated without the faceplate attached. (In addition to being a display face, it also contains a fine mesh screen to keep all that nasty RF inside the unit.) However, a remote display might be more feasible, as there would then be opportunity to permanently shield the front of the player unit. I don't think this idea is very high on empeg's list of things to do, though.

tanstaaafl.
