From my tests, it doesn't perform as well as say a E-MU 0404 USB.
If i knew what you were asking i might be able to respond (but the answer is probably no)

Does the EMU fo 24/192?

I can post measurements later. Yes it does and can even do 32 bit measurements. I think you'll find the noise floor is about 10 dB lower as well, but I'd have to verify that with my tests.

Not in practise (at least for me): "Macintosh analog operation up to 96kHz and digital operation up to 48kHz only at this time."

It does 32 bit internal processing with 24 bit I/O. I expect that that is pretty common as it is the most sensible way to use the 32bit wide processors.

I have run tests with 32-bit I/O I can post. Yeah, if the drivers aren't up to snuff on the Mac, I'd look elsewhere.

So, the Edirol uses CS5340 ADC and AK4385 DAC.

The E-MU 0404 uses AK5385A ADC and AK4396 DAC

The specs just looking at the datasheet shows what's theoretically possible.

Edirol FA66 (I cannot find my graphs for this one, but these are within +-0.2dB of what I remember, despite the sampling rate difference:
