I downloaded the software today, for a play. I suspect if you had a measuring microphone you might well be able to do a reasonable job of removing bass artefacts, and make bass/treble boost/cut changes relatively straightforwardly. With the caveats that horrendous speaker damage might occur if you mess it up. Looks interesting anyway, and I wonder if this might be a taste of more things to come from Naim in this area.
