The use of speaker impedance data to perform DSP on any speaker it’s connected to is quite interesting. Wonder how that compares to the more powerful and elegant Devialte expert series, which has that feature for only select speakers?
It really is very interesting. It is also not that hard to do yourself. The idea in the Technics amps is to correct for the amplifier however, not the speaker or the room. It won't fix room modes or calibrate your speakers in anyway. It will only correct for any deviations from flat the amplifier puts out, and, I believe, correct for the minor phase angle changes most Class D amps have in the top end.
It's almost like a feed-forward circuit, and it probably has strict limits in amplitude, maybe less than 1 dB of voltage correction. If I had a bunch of time I might even try this myself to see how my Class D amps compare before and after.
