I got Audiofire 2. Works just perfect. No drivers actually needed - only the Console app that allow you to manage channels settings and so on. The card itself as I understood operate under its own flash firmware and all it require is OS X built-in system's firewire audio driver, that's it.
Sound quality is exactly the same as with e-mu - simple basic consumer level. The most difference - it works
I created a kernel driver to fix the issues I and others had with the original EMU drivers for OSX.
The old driver did not work for me anymore after going to 10.9.5. Outright kernel panics. Playback ticks.
My driver also supports 176 and 192 kHz rates
