I've been thinking about replacing the M-Patch between my Rosetta 200 and Hafler P4000 with a stepped attenuator, which i think I would like to build.
I searching for DIY kits and plans, I ran across this remote controlled/ auto switching kit that runs about the same price as some of the manual rotary switched attenuators.

This design seems pretty cool feature wise. It is unbalanced in it basic form, but has an options to upgrade for balanced operation,option for 5 switchable inputs, can be modified to include switches on the box, not just a remote, which I would most definitely do.
While my soldering and DIY assembly skills are solid, my attenuator network design knowledge is still in its infancy, so I thought maybe I could turn to the real geekslutz to check out this design and chime in with your thoughts. Am I better off sticking with a tradition rotary switch, or is this design worth my time and money?
much thanks
