Kernel panics, worthless customer support, horrendous site support, sparse updates, ad infinitum. We've wasted more time than it's worth, constantly troubleshooting our M-Audio audio interfaces, pci cards, etc along with their respective drivers. It's beyond ridiculous. I'm astonished any Mac users actually invest in M-Audio products anymore. Needless to say we've pulled all M-Audo products from our studio and wouldn't consider any of their products ever again, under any circumstances. The very least we could do was add our two cents to the site for others to consider with the rest of their buying advice.
