The debate here, back in the mists of time, was NOT about deciding
which is better - it was about whether blind A/B tests are necessary
for deciding if there's a difference at all.  For deciding which is
better, there's much less of an obvious reason for using a blind test.

Look.  

An A/B test means nothing more than comparing two things.  Nothing more
than that.  

You want to decide if there is a difference between two things?  Then
most people (but perhaps not everyone here!) would agree you should
probably listen to both before making up your mind.  Oops, call the
doctor - you just did an A/B test!!

And for the tenth time, there is no reason such a test needs to be
"quick".  That adjective gets magically inserted in front of A/B by
anyone who wants to criticize it, as if it's the only possibility.

So are we arguing about whether the test should be blind?  Let's see...
you want to know whether there is a difference in sound quality.  Gee,
wouldn't it be a good idea to try to eliminate other factors which
might get in the way, like knowing in advance what you think the answer
should be?

There is simply no debate here.
