Excellent rubric, Per. Now these things can be measured.
Before Reboot vs. After, Estimated Match: http://bit.ly/xpSHqp
Before Reboot vs. After, Exaggerated Match: http://bit.ly/wVSkNp
The white trace represents "Mr. Nice Guy"'s response to white noise before reboot, the yellow after as per Per's instructions. The red represents the difference between the two (i.e, what it would take to change the former into the latter.)
The first EQ match is realistic; the second match is exaggerated to bring out the details.
As you can see, there's about a 2dB shelving lift in brightness above 6K, a gentle rolloff below 200Hz and maybe a .5dB drop around 1kHz in the post-reboot version.
