Mike:

Another example of ABC (With hidden reference ) is attached below. In this
test Bang & Olufsen's spin-off amplifier company "ICE Power" used this
method to determine whether there was an audible difference with a filter
removed from their class D amplifier. They found that listeners could not
tell the difference.

The fact is that very few audio companies do controlled double-blind tests
period... ABX or any other method for that matter. Harman is one of the
very few companies that do valid controlled listening tests, which is the
reason I work here.


Thanks to Sean for PROVING that ABX is not widely used in hifi design.
Thanks to Mikey the mckelviphbian, WHO HAS NEVER USED ABX, for posting this.
