Technical and scientific discussion of amps, cables and other topics.

Ooops. That was for you, Tubeguy, not RBNG... but anyways...

I just wanted to chime in and remind folks that "advertising specs" are not always done with scientific objectivity. Sometimes, standard or typical test methods are even purposely avoided to get the results that are desired, or to hide or minimize an undersired result.

It's like the "famous" (generic) speaker bandwidth spec. The industry default has been 20-20khz for... 20 years. But +/- how many db? 0.5? 1? 3? 10? 20? Speakers that have never even been measured have been sold with this "famous spec" typed onto a white label on the back.

In any case, I think most of these "arguments" are the result of overgeneralization.

But, take artwork for example. You can shine any color light you want on a painting or use a lamp with any color temperature you want. But ultimately, only full spectrum light will give you accurate color rendering. If someone prefers art illuminated with low-pressure sodium orange-yellow light, then that's fine. But it's not accurate because they like it. And it's inaccuracy CAN be measured - quite easily.

Cheers,
Presto
