When you test your DIY mods...

[Bubinga99]

If you do a modification to your system--cables, crossover rebuild, driver change, or whatever--have you found a definitive music passage or song that serves as your "go to" test that always highlights any improvements, or non-improvements?
(Especially interested in those that have worked best with Polk SDA apeakers)

It's probably wishful thinking to hope there's something so clear-cut and consistent, but thought I'd ask...

What are apeakers? J/K:)

I use Rush Moving Pictures and/or Michael Jackson's off the wall the SQ on both of these are great.

Nine Inch Nails closer is great as well, plus these picks have great bass.
