I can't find any before/after audio samples - can anybody point any out? I'd have thought it's about the first thing you'd do to show off the differences (I get it - it might not (probably won't be (?)) be tuned for my particular speaker... Still wouldn't hurt to hear an example).

the DSP at play here is more than just an equalizer, and as such an audio file cannot be produced to illustrate the differences in a meaningful way to unknown target speakers
