I'm not suggesting that you or anyone else do so. I am speaking of
instances
when the listener is convinced via a DBT that there is no real difference.
Do
you think the previously percieved difference comes back with sighted
comparisons or stays away?

I think the difference would stay away. I really subscribe to school of
thought that sighted listening is more a more engaging experience, therefore
rendering DBTs invalid and useless.

I just picked up the Randi controvery on this forum, so I don't know
first
hand whether JA or anyone else at Stereophile actually reviewed the
Shakti
Soundfield Optimizer or the Bybee Quantum Purifiers. However, it would be
disappointing that a magazine for serious audiophiles would review
products
like these without some discussion of the science behind them.

Audio may be an art, but when an audio product claims to operate on the
quantum mechanical level to regulate the flow of electrons, I think it's
time to break out the oscilloscope and multimeter. Don't you?

Yeah. But Mr. Bybee seems to have some pretty serious credentials.

No one's disputing Jack Bybee's credentials. But then, ever Amar Bose has a
PhD in Electrical Engineering from MIT, no less.

So do people really go
back to hearing "imagined" differnces when the go back to sighted
listening? If
not, why did those "skeptics" think they were hearing differences during
informal listening and if so, isn't that something to pay attention to?

I don't have a dedicated listening room at home and my listening habits
usually involve the music playing and me multi-tasking - web surfing,
working, etc. So I am not sure whether that constitutes a DBT but I can
definitely tell the sonic differences among the various speakers that I have
owned over the years on the CDs that I know well.

So again, I don't really know whether sighted listening is all that
different from unsighted, particularly since, I would assume, all the
Stereophile reviewers have golden ears.
