i find it interesting that even factory mods can diminish the perceived value of a component. for instance, when i was selling my 508.24, people were adamant about wanting an "original" 508.24 (which mine was), and not a 508.20 that had been upgraded by meridian. although an "upgraded" 508.24 is functionally identical to an "orignal 508.24, the upgraded unit would fetch a lower price for some mysterious reason. but whatever.
