My theory on ATCs sounding better louder is simply that they're accurate so they sound more like live music the closer they get to the volume of live music. Other speakers are less dynamically accurate but sound subjectively better at low volume.
I wonder if there is a relationship between the ability to handle high volume and better sound at high volume. What speakers sound great at low volume but can handle high volume?
