RE Paul Barton's 1/4 dB of FR change after break-in.While this sounds like a small amount, when translated into the amount of signal aberation it would take to create a 1/4 dB FR change, this equates to approx. -31 dB. That is, if a signal aberation that was occuring 31 dB down from nominal changed or shifted, then it could cause a 1/4 dB change in the FR curve.
We can hear signal aberations that are -31 dB down, especially if it is a hysterysis type of signal distortion, rather than straight forward HD.
