I'm planning to build a passive preamp-- simple thing with just an input selector and stepped attenuator. It will have no active components and no gain. Though I think I will try adding Tangent's Linkwitz crossfeed (also passive) with an additional DPDT switch to optionally bypass it completely.
My question is, where should I ground the enclosure to? On my amp, the case is connected to the common L+R input ground. But on the planned preamp, there will be multiple inputs. Should I connect all of the input ground wires together and tie the case to that?
