At only $40 the TekRepublic TH Pro 7.1 gaming headset is an inexpensive way to try out virtual 7.1 audio.  The software it comes with allows a nice amount of control over the DSP Mode and Output Mod as well as letting you move the perceived positioning of the virtual speakers.  It also allows you control of an equalizer and a range of effects you can apply to your audio.  Modders Inc also reported the microphone to be of decent quality for the investment.  Check their full review if you are in need of a reasonably priced USB headset.

"Tek-Republic, being somewhat of the new kid on the block, is a company based out of Pasadena, CA that is at the moment primarily focusing on gaming headsets and mice. We have the good fortune to take a look at the Tek-Republic TH Pro Virtual 7.1 Surround Sound USB 2.0 gaming headset."
