Sense is a unique innovation by Colin Wonfor, based on several methods of feed-forward error correction he used in other applications. The following is an oversimplification:
In the case of the EWA M-100 Turbo S, 'Sense' is a feed-forward error correction system that compares the audio signal at the loudspeaker terminals to the input of the amplifier, and dynamically corrects for any difference or losses detected.
(This means an additional set of wires needs to connect to the loudspeaker terminals and run back to a designated terminal on the amplifier. This is not bi-wiring, nor does it create a short circuit. No audio signal uses these wires.)
What is 'Sense' correcting? Starting with any losses on the loudspeaker cable itself (you shouldn't have any losses there - you ought to using EWA), back EMF from the loudspeaker and assorted secondary effects of the crossover network all manifest themselves electrically in the loudspeaker cable and amplifier.
By comparing the the signal at the loudspeaker terminals with the input terminals at the amplifier, every difference (that isn't voltage or current) is corrected, in effect using the amplifier circuit itself to 'EQ' the signal in the analogue domain, utilizing fully the dual differential nature of the EWA circuit in the M-100 models.
So what is the difference? You might expect it to be pretty minor, right?
Wrong. Sense really brings a new level of control and presence to the sound you hear. It can even be seen, on bass heavy material the output is clear, loud, extended - yet the loudspeaker bass drivers appear to move and oscillate less. You'll have to hear the difference, I'm afraid there's not much to compare it to.
