Meadowman...The CI amps use a module (UcD) that is similar in concept to the ICE module, but with some topography changes that address what is perceived as a weakness of the ICE nodules: HF response variation with load impedance. As you know, loudspeaker impedance varies greatly over the audio frequency range, and this has been blamed for less than ideal HF sound from these amps.
