I will be brief. I have heard both the CW3 and CW4 in a dealer's space in Chicago, side by side, same sources, same amps, same music. The CW4 was head and shoulders above the CW3 in width and depth of soundstage, much smoother and balanced in all aspects of HF, Mid and LF. Not sure what else to say, but then based on your previous posts in this thread, you probably won't believe me, nor care. And honestly, I moved away from Cornwalls years ago and have had La Scalas/Khorns/KPT-904s /Heresy 4s since then. And you can't think of any advances in audio engineering in the last 17 years, really?
