Blind or Just Deaf?

Does anyone following these forums actually insist
on doing a "Blind" listening test before laying out
several thousand on a new piece?

Or is a little Herb wax all you need to slip into something comfortable?

I do not necessarily mean in your own listening room
as that is difficult to do. If you have to bring your own
Amp or speaker to a retailer then you have done what can be done.
Or you may be comparing two items you do not own.

Finally, would you pay $ for a blind comparative listening session
at a properly set up facility?

I have an idea I think may be a good one.
Not from Dwight either.
