Yeah, I knew what you meant. Not really any more "wireless" than a CD player with a remote control, though. Still gotta be wired to your setup. But you CAN pass 192kHz/24bit stuff.
I pass my Apple Lossless stuff wirelessly from my desktop computer upstairs to two different Airport Expresses that are located downstairs; one that's in my bedroom (analog) and one that's in my main system (digital). I can pass to one Express or the other or both at the same time. And with some of the same files on my laptop computer, I can pass two different sources to each Express, separately. I can control it all with my phone, too. I can also control my upstairs desktop with some software that's on my laptop. All through wifi.
Yes, I am limited to 44.1kHz/16bit but the vast majority of my 420GB of stuff is ripped from my CD collection so that's not an issue. I did go ahead and rip a lot of my higher resolution stuff that I didn't also own on CD to Apple Lossless, though, knowing that I may have some other way of passing it that supports the higher resolution in the future. As best I can tell that stuff gets downmixed to 44.1kHz and either 16bit or 24bit (not sure which, really) by the Airport Express, now.
