Default Mains filter test results

We didn't worry about setting up a blind test at this stage, as my
concern was simply to find out whether there was a difference,
perceived, psychological, whatever.

Anybody with a clue about experimental design or psychology could
predict the outcome of your test without bothering to do it.


The implication of what I wrote before was that if there appears to be a
difference (whether real or psychological) then it's worth the effort
and hassle of setting up a blind test. If there's no difference apparent
using a straight test then there's no point wasting time with blind testing.

However, as a straight test concluded that there was indeed a difference
(whether that difference was real or psychological is a matter for
debate, but the fact that three of us all heard the same effects would
suggest that the difference was indeed there) then it's perhaps worth
setting up a blind test.

As I appear to have won an Isotek power cable, at least for the time
being, I may well set up a blind test next time I've got a few hours to
waste. If I do so then I will of course post the results here.
