Hello! you must either really bored or very curious to open this up, and your yamaha msp7's as well. But it's interesting to see though!
Anyway, I'm thinking of getting the Saffire pro 14, been seeing alot of good reviews online lately. I got a question about the FW and what computer you're using. Are you using a PC or MBP? 'cause I know this is Firewire 400, and the newest MBP's are 800, and that means you'll need the 400-800 adapter right?
Right now I'm using ye' old macbook, the core 2 duo one with a firewire 400 socket, but I'll be buying a new MBP in the last quarter of the year when I ORD.
