this is pretty cool stuff. seems like a pretty painless way to patch into the world of Ethernet, without sacrificing your analog toys. max sample rates 96k, 48k on the usb one, but that's noes an issue for most things. id love to see an 8 channel, and ultra high sample rate model soon, for audiophiles and home theater applications. wifi support cant be too far away either.
