ABX or some other form, but it was somewhat academic in methodology and

What about on Smudging the room (or not)? Should the Shaman be also a
Healer? There may be skewed results in the Scientific approach, but isn't
that what we're trying to get away from? (: Seriously, Dr. Who talked about
a race who were intelligent enough, but who spent all of their time trying
to escape what they felt was the trap of Rational thought. Maybe these mods
are rituals for returning to the original (ultimately Enlightened) way of
hearing, rather than for us to expect a static, Absolute performance upgrade
achievement. We wouldn't be able to appreciate that at all times, anyway.
Now, where are those beer goggles? (: (Now, Hash generators...)
