How to add more digital inputs on dac?

I just purchased a V-DAC thinking the switch on back would control whether the optical or coaxial input was used, but it appears to switch between the optical/coaxial and usb instead. I have two devices that output optical/coaxial: Denon 1940CI and a squeezebox.


Can somebody recommend a decent optical or coaxial switch that will allow me to have both units hooked up to the DAC? I'm hoping I can get something fairly cheap, small, and attractive. Or would there be some cheap way to utilize the USB instead?


Thanks!
