I seem to get the crackling sound as well, but only if I turn up the "SRS Definition Level". At 5+ circles, while playing a rock heavy piece of music, something with a good percussion and crash to it, that I do get some crackling.
I kinda can hear it at 1 circle, but its so hard to make out. Though turning it all off makes the music feel flat now; which seems worse.
I am growing to dislike it more and more. The problem I have with it is how it functions with windows and games, and settings. It creates a new "audio device" and then the game/music player/movie audio gets done through it. Which is fine, except the audio effect is not always desirable; and actually closing the program is a huge pain. For instance I do not like how it changes the audio in Team Fortress 2. I try turning it off, by clicking on its GUI, which works for desktop applications, but in TF2 the audio is still worse. I then try closing the program, except there is no simple way to do so; so I then force quit the program, only to cause more headaches because of the audio device setup it uses, which requires a reboot, with SRS setup to not automatically start.
Which is really really annoying and I play TF2 and other games with similar issues often, so right now I am leaning towards not buying it; even though I like what it does for web video and music.
