A second generation from that lossy-sourced 320 would probably start to get pretty grating, though. If you're thinking of doing it for artistic reasons, though, I'd say you're more likely to get better results from a judicious selection of high- and low-pass filters, with a flanger or two thrown in.

      Just to expand on what eponeponepon said, digital generation loss (by transcoding/compression) sounds quite a bit different than analog generation loss.
