Yeah, it's not a general loss of quality. He actually showed me a really cool YouTube video that explained what is lost with compression, where the person making the video played the same passage of a song compressed and uncompressed, and then showed visually the parts of the waveform that were clipped, and then played the clipped parts isolated. It was a lot of high-pitched, tinny noise, presumably from the upper end of the high hat cymbals and stuff. Wish I still had it handy.
