Maple Tree Audio makes custom built router switches. They call these Engineered to Order (ETO) Routers. I have one that does 4 in, 1 out (RCA) and it's nice looking and well built. You tell them what you want and they get back to you with a quote. You can even choose the type of wood for the side panels. Great company to deal with and made in America.
Amplifier and Speaker A/B switcher
I'm looking for a well made switcher that has the ability to switch between two amps (rca cables) and two speaker pairs (using banana plugs). I am only seeing devices made in China and they don't appear to be of very good quality. Can anyone suggest a high quality device safe for my equipment and not to degrade audio quality? Thanks.
