Hi all, I'm wondering if a Z Switch box will be what I'm looking for. I have two pre amps (Don Sachs line stage and a Decware ZMF OTL ). I also have two subwoofers.

If i'm understanding correctly how the Z Switch box works, I can put the z switch box between my Zen Torii +  2 subs and my 2 pre amps. Each pre amp going into input(s) and the outputs going to my Zen Torii and subwoofers. This would allow me to switch between pre amps and output signal to my Zen torii and subs. Does that sound right?
