I vote for:
RME HDSP 956? and Multiface 2.. you can hook up 2 and have 16 in and 16 out.. its possible to have 3 but a lot of people have trouble with 3 multiface..
multiface rocks.. invest the rest of your cash into UAD-1 plugincard..
just another opinion from george

it's not the only truth but you may think about it..
Aurora has to little lowend in my opinon.. bassarea missing.. dakota too old..
