9 folks with DSP speakers say Improved 0 say no improvement.

Improvement will vary depending on how far negative you were calibrated.

By the way the reason why I suspected it had to be +3.0dB exactly is a I'm totally amazed with all the golden ears on this forum that can hear Axis, Unsampling, Differences between G68/861, and Apodizing never noticed the lower you calibrate the worse it sounds (including me for that matter). I thought the "golden" value was out of reach. But it's always been available. All I did is find more range and that +3db in MSL really means 0dB of Gain through the Preamp.

If you think listening to music is fun, try learning an instrument.
