I bought one and think it's very good, my criticisms are that the highest notes are weak, its seems to lack oooomph, and compared to my teachers Kemble lacks resonance. I have all the settings at default
I sometimes wondered if the tone on a CLP1XX model also had something to do with the built-in speakers? Very often, people have put their instrument through a PA system or even through an amplifier, and a whole new level of sound is realised.
Having said that, I have heard that the iAFC feature only functions when the sound comes through the speakers and not when amplified through the out ports or through headphones.
