I'm fully aware of the effect, a skeptic at heart, and I find that I
still fool myself all the time into thinking I hear differences when I
don't.  I wrote an ABX tool because *I* needed it to use for my own
testing.

You're on Linux, right?  Just grab and build Squishyball:

svn co http://svn.xiph.org/trunk/squishyball

it's a lightweight, standalone double-blind tester.  Hand it a few
comparison files, and off you go. It runs in a terminal.  It can run
in a few modes, the manpage details them.  It's useful for
non-rigorous testing too.
