What is your opinion of this product?
Great interface. I bought mine used for cheap, it has Onyx preamps, very clean and clear with my Neumann TLM-67. The Focusrite ISA One I use is great, but seemed to colored with the 67. The Cirrus DA/AD converters are excellent, check the specs! Very satisfied with the sound quality. Nice build quality and I love the onscreen mixer/router, super easy and effective. The only thing I don't like is I believe its not true ADAT expandable, only SMUX and with another Blackbird, so I've read , but I'll have to see if I can get it to work with my Behringer ADA-8200. Don't hesitate to get one if you need clean preamps , great conversion, and a firewire interface.
