That is a good interface for its price. I am not happy with the firewire latency and looking for a thunderbolt interface but other than this issue this is a very sufficient audio interface for this price range. 2 headphone preamps really great. Instrument preamps have pretty good headroom and satisfying. Not the best but definately is a good choice.
Sound quality is crisp though and there's almost nihil latency! The reason I gave it 4 stars is because it is great for personal use, but as soon as you need to perform live with multiple mic's attached, there might not be enough outputs for you to split the signal into a PA system. Personally, I think the default routing in MixControl is also quite silly, but maybe that's just me. Also, the power supply cable is very short.
