The price comes from it being VERY rare in North America... Still $350-$400 is excessive. To have an understanding of the UniLink bus well enough to make a Multi-Changer adapter is not easy--then you have to make the MCA and that requires a lot of work including finding also very hard to find UniLink female connectors! I guess what Pete *might* be trying to say is use an analog MCA (like the XA-C30 or XA-U40--no "D") and then make your own (active) optical switcher. You can even buy an active optical switcher, however they are also not very cheap. I'd imagine at least $150-$200 for a device like that... You could also go with a manual optical switcher and just change the source yourself (some use push buttons and other more expensive ones you can use a remote); but changing the digital source yourself is a little more involved than just changing sources on the HU. One of these is not necessary for more than one changer, only for more than one *digital* output changer to be connected via digital output. You could use a much cheaper XA-C30 or XA-U40 (discontinued) MCA for analog changers. Furthermore if you have only one digital changer you could connect other another analog changer(s) as well as the digital one using the standard MCAs. Only when you have more than one digital-output changer does it become an issue. Even then you *could* always go analog on the other digital-out changer(s) keeping just one connected digitally...
