Ok cheers for the answer.. does makes sense.

just being abit cautious as cards like the motu are top end of my budget and want to make sure its worth the extra cash. is it a huge improvment from say an m-audio.

Im intrested in the m-audio one because i can run it from my usb port. ive only got a 4pin firewire. runing the soundcard from a non mains power source like a generator would proberbly be a big no no.. i might be wrong.

Thanks again
