Dane, I think the question is more about performance than audio quality. Dana, the audio quality is identical whether compressed at level 0 or level 9999, but it sounds like you're wondering whether your machine can handle the higher compression levels without audio breakup, stuttering, crackels, ticks, pops, etc., from a machine not up to the task. I'm going to go out on a limb and say that, with today's machines mostly all running above at least 1.5 gigahertz processing speed, the answer is in all likelihood no. I'd not be surprised, though, if you did have problems on slower, less responsive machines such as netbooks since everything about them is slow as compared with your average desk- or laptop.
