Hi Roggae
I don't know if this will help you but this is what I use to switch between inputs as one of my preamps only had one set of RCA inputs. It has a nice build quality IMO and I have not experience any sonic degradation in the systems I've used it in.

I hope this helps and good luck with the search.
