Summary: USB powered preamps in the audiobox were not robust enough to overcome the noise level in the device. I added an extetnal preamp and it now works well. However, this would be a one-star device had I not made it work by combining it with another device. It did not work on its own as advertised.
Great entry level interface for the money, but not perfect

Summary: For the price, this is a perfectly acceptable entry-level USB audio interface. It is extremely stable (I used it with Windows 7 64-bit), easy to use, and the pre-amps and converters sound pretty good -- REALLY good when you consider the retail price. USB 2.0 will always be a little slower than FireWire for a couple of reasons, so be aware of that if you are buying a USB interface, but also know that you can't hold that against the Audiobox, it is no slower than any other...
Perfectly Average, nothing blows me away, but nothing is wrong with it.

Summary: I am not blown away, but it gets the job done. It is simple, nearly plug-and-play, and works. The knobs are a little sticky sometimes, and I notice a little buzz from both inputs, but not enough for me to really care about. I use it as an interface in my home recording studio, which basically is comprised of this, a microphone, and a keyboard.
very easy to use, solid for minor recording, but some interference problem
22 August 2011
Summary: I bought this to use primarily as an external DAC/headphone amp for listening to music, along with some minor recording stuff. I got it, and it works great for recording, plugged in and worked right away, no fuss at all, which is very nice, but the issue I have is that i've noticed some interference from my computer, particularly when I have the headphone volume set below around 80%. I have to tweak the settings on the audiobox just so to get rid of it.
Summary: I have used this for a year now with great success in 32bit Windows XP and now with 32bit Windows 7. Very stable, very reliable. However, there are two issues. 1) lack of 64bit support for XP/Vista/7 2) it is real easy to overload the pre-amps. Plugging in my electric guitar into the instument in, I have to turn the volume knob on the guitar down 3/4 of the way and turn the level on the input on the audiobox down all the way just to prevent it from clipping.
