What I did find incredibly joyous about the US 2000 however, was its method of monitoring for headphones. On a budget interface, you would only expect to see a knob that controls the ratio of monitoring sound coming from the computer verses the combined inputs. However, the US 2000 generously allows the user to set both volumes separately, which means that fiddling with knobs to strike the perfect balance between volume and ratio is a thing of the past! This is unlike the younger cousin, the 1641, which I am consistently bothered by on a day to day basis. I also find the meters very useful for maintaining balance when recording.
The drivers for the US 2000 are a dream and run incredibly smoothly. Thus, this audio interface is just like any other proper interface. Works. No questions. No need to explain.
The preamps on this are a little bit better than that of the 1641's I have observed. They seems to have a little more excitement and energy. However, that is not even the main draw. To be truthful, the lack of midi makes syncing latencies when doing midi a little bit frustrating, and that is why even with all of its improvements I cannot truly recommend the 2000 over the 1641 or the 1800.
