Speaker surrounds/burnin

Ok here it goes...I ran a arye disk/track 4 after reading some obscure blogs (wish I would have saved/one was from vandersteen) about getting surrounds moving/burn in.Thing is I did burn speakers/amp in using this but never really got the speaker surrounds moving.
Totally different sounding than the sound I had before.Bass/scale/sounstage/timber greatly improved.
Dynamics are off the hook...saved (Some components) from the chopping block.Just wonder if anybody else has done this w/pos results.
