Windows iTunes- AX- Toslink- DAC Bit-Perfect?


Hello all,

I recently read that Windows Base System (iTunes) to Airport Express (with digital output) may not be able to by-pass the k-mixer in the windows.
If this is true, how is the digital signal get alter in the k-mixer? (Upconverted to 48k then down convert to 44.1k?)
Is Windows based iTunes -> AX via mini toslink -> DAC Bit Perfect? What if the remote volume is disabled?

Thanks

My understanding is that Airport Express is in fact the ONLY way to get bit perfect output from iTunes on a PC (Macs allow bit perfect output via other ways). I've read posts where people have tested it and confirmed it's bit perfect.

I use a (Red Wine Audio) modified M-Audio transit as a source from iTunes with the "remote volume disabled" and it sounds fantastic. Not sure what it does or does not bypass, but I hear the computer's other beeps and such through my headphones, which I actually don't mind because I'm using my computer while listening (for me, it's a nice feature).
