Which is the better option for a sub-$500 Firewire A/D interface? Think I've narrowed it down to those two. Anyone have an opinion on the quality of the A/D converters or the general reliability of either company's products? The Saffire's about $100 more but has some additional capabilities in terms of plugins and software integration. One other question: I need more of a Pad than a Gain on each channel as I am coming from a preamp with a strong signal level. I see a pad button on the MAudio but not on the Saffire. Am I missing something?
