Why not? What is there about controls of listening bias that would preclude you
from hearing real differences?

This is a serious question. I ask because I've been there myself and subjected
myself to a bias-controlled experiment.

But you don't have to "bet" on it. All you have to do is put yourself to the
test, with bias controls implemented a (levels matched, blinded listener and
start synch) and report the results.

Amrstrong was a professor of EE at Columbia University. Do you think he
came up with his innovations purely on trial and error, or do you think
he had ideas first, and knew how to make measurements to turn the ideas
into innovations?

This is the first time I heard that Armstrong worked mostly by trial and
error. Can you provide some link?

Yes, I would agree whole heartedly - familiarity with live unamplified live
music is the only legitimate comparison.

If the answers are not simple and easy for the layman to get then I am not that
interestred.

So why

Because it looked to me like bait for a shell game.

If that was the question then it was based on a false premise. Bromo never
claimed "no one knows how to make measurements that shows those products work."

Seems like a legitimate

Perhaps it does until one realizes it may be premised on a flase assumption.But
then you are speaking for Tom here. I thought that wasn't even allowed. Oh
well.

Please read with more care. Here is what Tom asked:

"Again what should we be measuring to confirm 'amp/wire' sound that we
haven't already done?"

To which, Mr Bromo replied:

"It might be that no one knows. "

The question posted by Tom was how did the designers design those
products *if, as Mr. Bromo suggested,* no one knows how to make
measurements that show those products work.

Where is the false premise? Do you see a difference between "claimed"
(your word) and "suggested"?

That would be what I said - to clarify, there may be a listenable difference
in the amp-wire-speaker combination - but based upon the way measurements
are done, it is possible we have missed something. No shame in that.

I's nothing to do with measurements - there is simply *no* evidence
that *anyone* can hear differences among nominally competent cables.
Until the premise of 'cable sound' can be shown to *exist*, why should
we be measuring anything?
