Dave,
I have the Audiobox 44VSL. If it is compatible with your machine, it does a great job of recording. It is a little noisy while monitoring and seems to pickup interference from the computer when the computer is busy (blips and other noises way in the background when disk writes or screen redraws occur). However, these
are not recorded and are very much in the background. I only ever notice them when no audio is actually playing. I have read on Presonus' forums that swapping USB cables
may help, but since I've gotten my system stable, I don't want to mess around with it.
Which brings me to my caveat: this interface is
very finicky about which USB busses it works well with. When I first got it, I could not play back without pops and clicks and/or distortion. Over time and with a lot of tweaking in Windows, I was able to get pops and clicks to stop. I now record at 24/96 and the interface performs beautifully. As of today, Presonus only has a
beta driver that appears to solve most issues in Windows 7. If you buy this, make sure you get it from a shop with a liberal return policy, just in case.
Regards,
Dan
