I'm sure a lot of people are waiting on the new Joshua Tree to make its way out into the world, I know I am together with the Volumite. The SPDIF mux is also on my top 5 list of things to get the second they are available :) I missed out on the Toslink modules last time around. I was so focused on getting the Buffalo that it totally slipped my mind. i cant speak for anyone else, but I'm willing to get it with the new Toshiba TORX receiver, even if it turns out to only support 96khz. I have not yet found any sound card that will transmit 192khz via the optical out, only coax. I'm sure there are sources that will do this, but I have yet to find one.
