SSL Alphalink with a couple Presonus boxes for 40 IO total. 48 outs if you count the Hearback system on ADAT. This all went into a SSL MadiXtreme card over optical. Works great.
I'm just now switching to a RME HDSPe MADI card to use TotalMix for some stuff and have the SSL card up on eBay, going for a good price.
