Soundcard along the MPC!

I am buying the 2500 in near future, so my question is, what firewire soundcard should I buy to use up all the outputs of the mpc? I want to lay down as many tracks as possible. I made my search, but I want to know your suggestions. I have a great Focusrite Saffire LE, but it has too few inputs. If I bought a mix, i would still have just 1 balanced input on the soundcard, it would only help to put effects on different tracks. Thanks for help!

i use an RME MULTIFACE 2... i run 4 mono outs and one stereo out... thats 6 outs...

the most you'll find in a unit is 8 i/o... plus digitals i/o and whatever else... i have not seen any units with more then 8 i/o... or at least at this time i dont remember...

anyways, RME and LYNX are some really good buys for the quality... i wouldn't suggest any other brand under $1k...

i use a Phonic helix18 firewire mixer(14 inputs). it can be used as a soundcard.
