Don't think there's any way to reliably run 2 of them together. I suppose it's time to move forward in time anyway. (like I said, when I can afford to, anyway)
I'd love to get an RME fireface 800 but too much $$$$. I keep hearing good stuff about the Audiofire 12, which would give me 12 ins, I'm just worried it may not sound as good as the Q-10.
I've always been curious as to why no one ever advertises the Echo stuff. You never hear anything about it. Very few places sell it. Reviews are VERY rare. I'd hate to buy into another company that goes under and leaves all it's products orphaned like Aardvark did.
