There are less expensive interfaces that come bundled with plugin packages (TotalMix has a limited number of effects available) but I think the audio quality, build quality and rock solid driver stability make the UCX a better choice

Rock-solid stable drivers, excellent sound quality, powerful routing options via TotalMix.

But really what you pay for is the absolutely perfect uncolored sound quality (the mic preamps are better than most stand alone preamps I have tried) and the rock solid reliability

Simply the best quality sound for PC audio interfaceBetter than UC that comes with USB 2.0 only, but UCX model has USB 3.0
