The VAC Statement has been developed with the critical ear as the major arbiter of quality, with
both conventional and unique measurements providing insight and guidance as necessary. The lack
of emphasis on measurements is due to the fact that engineering's arsenal of equipment and
techniques do not operate on the pattern recognition principals that control human perception of
sound.
In the immortal words of Daniel von Recklinghausen, if it measures good and sounds bad, it is bad.
If it measures bad and sounds good, you've measured the wrong things.
For those concerned with test bench performance, the following describes typical measured
performance when operated at 120 VAC, 60 Hz.
