EASER Wow. I was going to respond but someone beat me to it. All I was going to say is that I respectfully disagree. My main reason for using it is that it doesn't slow my system down as much as VolumeLogic. And I don't like OSS 3D because it makes my System Preferences slow to a crawl when I open it. AudioHijack is nice, but I haven't found the kinds of effects I can get from these other programs. Given the options available to me, I opted to stick with iWow. It's not perfect, but I haven't found the sound to be too intolerable.
