RE: No: accuracy has never been defined

Posted by Phelonious Ponk on June 29, 2010 at 10:27:20:
The problem is you created my definition of accurate from the part of my (short) post in which I was expressing my personal opinion. The part in which I was defining accurate shouldn't have been hard to find, it was right up top and clearly identified itself:
"How faithful is the output signal to the source signal? The more faithful, the more accurate."
Is this really simple? It's not terribly complicated. You want to measure the accuracy of a preamp? Measure the analog signal that is being fed to it by the DAC, across every reasonable, measurable parameter you can, then measure the signal coming out of the preamp by the same metrics. The variance is the inaccuracy. This used to be SOP for manufacturers and reviewers. Are there things we cannot yet measure that may also be audible? Maybe. Measurement is not perfect. It's just a whole lot better than deciding it is meaningless, tossing it off, and declaring that everything is subjective out of one side of our mouths while swearing gear that is deliberately colored is more natural out of the other. I'm not accusing you personally of doing that, by the way, but it happens every day in the audiophile community.
