Hey there
I’m trying to figure out the best way to step up my game with a new interface
(and a spl mixdream) but everything I see (UA/Antelope/MOTU) is pretty much made for mac
and I was wondering if you guys know a better way to go ?
Must be 16 analog outs at least.
thanks 
You could combine this: MADIface USB - RME Audio Interfaces | Format Converters | Preamps | Network Audio & MADI Solutions with this: http://www.ferrofish.de/en/en-a32.html
Or do something with ADAT on another interface that provides preamps etc. A Fireface UFX or 802 (RME drivers rock) combined with one or two ADAT devices. Plenty out there in different price ranges, for analog summing you should go for great converters of course.
