As a newbie, I realize the immediate need in this thread was for three inputs, but would the CI VPC-2 controller also be an excellent switch candidate for two inputs, to connect a headphone amp to a source or preamp? One preamp I'm considering does not have a tape in/out --just two pre outs. Would it be a good idea to use the VPC-2 after one of the pre outs to switch between the CI VPH-1 head amp and ,say, a sub? Or would it be better to place the controller/ switch after the source (SB2, SACD player) and before the preamp? I worry that any attenuation and/or connection in the chain is bound to detract form the sound somewhat. And this assumes an SB2 (Bolder full mod) could drive the VPH head amp directly.
Thanks.
