Focusrite Scarlett 2i2 by Sundaytrucker
Using the new drivers from Focusrite's website, installing this on a Windows 7 64 bit setup was a breeze. Performance has been rock solid in Sonar as well as computer related audio tasks such as movies and games.
Box is built tough (aluminium casing) and the knobs feel nice and sturdy.
I don't do a lot of vocal or mic recording tasks as I'm a guitar and bass guy who records direct for the most part, but I can tell you the preamps in here are a nice upgrade from the Art Tube MP and EMU 0404 pre's I was previously working with. Using an M Audio Sputnik on a female singer and cutting my brother's acoustic, the sound quality is much cleaner, detailed, and a lot quieter as far as background noise goes.
Sound wise, I still prefer to use my Stealth pedal for tracking bass and guitar direct, but going direct into the Scarlett isn't a terrible option by any means if that's what you are getting this for.
Overall sound quality of the unit is on par with the Emu 0404 to my ears, and that's a good thing because I think the Emu sounded good, just wasn't happy with the pre's, and I was having a lot of issues with the Driver's on Windows 7.
The included Plugin suite sounds great and only adds to the ridiculously good value this package gives you. I highly recommend getting this if you are in need of a mobile recording solution, or are on a tight budget for home-based projects as well.
