Stereophile likes to use the Step Response to measure speakers in the time domain. John Atkinson wrote a nice article explaining why he uses the Step Response graph. I personally like the step graph much better than the impulse graph. To me, it's much easier to read.
JA is in a good position to discuss this measurement in relation to subjective impressions because he's measured many more different speakers than anyone else I know. I'm not aware of any research (DBT) which proves or disproves the value in a "better" time domain behavior, other than it's relation to frequency domain behavior. As Floyd Toole said: frequency response is merely an inferential measurement of time response. (or something like that).
JA talked a little about his subjective impressions related to good and bad step response at 52:25.

I've done some measurements with REW using different DSP filters which can improve my system step response. In terms of stereo imaging, I totally agree with JA's description. The stereo image is more precise (side to side, front to back and top to bottom) and the music is more accessible to the ear.
Does anyone else have this experience after having improved the time domain response, with DSP or otherwise?
