agreed with Gary, I have been using duet since 2008. It's just simply awesome. I upgraded to Duet USB. The sound is amazing even with my cheap dynamic mic (shure sm7b). The only problem you might encounter with a duet is that sometimes when you hot plug it in (with logic closed), it's not recognized, but just unplug it and plug it back in (or try a different usb port), then it should work again. hope this helps. just noticed it's like 7 months ago, oh well. :-)
