The only way to know for certain, is to try it on your system/listen for yourself. In theory- It will provide cleaner(more faithful to the recorded material), improved sound, which of course: some don't like(not their taste). Anytime bass is increased relative to the rest of the audio spectrum, the "rest" will SEEM attenuated. The up-side of purchasing used Kimber products is that, should you not like the effect; they can be resold at little(or no) loss and usually- quickly. Keep the runs the same length(hi/lo, same channel), to avoid any imbalances.
