And in regard to your Dyns.....listening alone is not a very good objective measurement //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif It is highly likely that your perception of their sound changed more as you got more used to them, which could easily account for the change you heard without invoking any change in the actual response of the speakers themselves. That said; I'm not saying there couldn't be some slight changes in the actual sound characteristics. But this would require objective measurements to determine why, where, and how much....and not simply "listening to them".
