I use my PC mostly for sequencing/arranging on keyboards, sometimes editing digital audio, sometimes I just want to listen to awesome music that I can just turn up and just about bathe in.

My own music that I record sounds cleaner and more accurate

3 or so feet apart, music sounds clearer, cleaner, and more widespread (I am playing PC audio thru a Mackie Onyx 2x2 USB interface right into the speakers).
