Great thread!
I get a lot out of adding "handwork" that helps my systems sound and look good.
For example:
-Rebuilding a Lenco L75 in a custom designed phenolic resin plinth
-Designing and building custom stands for my Quads
-Building custom stands for Monitor Audio MA-3's, modeled after an Audio Note design.
-Adding an exotic hardwood faceplate to an old tube amp pulled from a console . . .
Fun, fun, fun!
