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.

Proper valid listening tests cost lots of time and money, money that most
companies feel is better spent on marketing and advertising -- or profit
margin. To a large extent they can get away with it because there are few
checks and balances. For example:

1) 99% of audio equipment review magazines don't do valid controlled
listening tests and their objective measurements of the equipment is
often missing or is incomplete.

2) the consumer is increasingly less able to do a valid comparison of
products in the stores, as audio equipment has become a big-box store
commodity

3) The standard specifications (amplifiers and loudspeakers) given by
manufacturer's are largely misleading indicators of performance and sound
quality.
Making a purchase decision based on these specifications is like rolling
the dice in Las Vegas..


Unfortunately, none of the above 1,2,3, hocus-focus prove that ABX is
a valid and effective means to confirm whether the subtle differences
audiophiles hear physically exist or not.

Eddie, the man says it's one of a couple valid ways to test for difference.
Once again the world is amused at your incredible blindness.

Are you in love with this gentleman calling himself Mr. Sean Olive or what
??

It's a matter of respect, no surpise you're unfamiliar with it.

You tirelessly labor the religious gospel for him. Let the man speak for
himself.

He just did, you twit.

This is an open forum.


Otherwise you'd not be allowed in.
