What's a positive attribute?

I am specifically talking about the attribute reviewers refer to as "revealing". In every review I have read this is treated as a positive no matter what it is referring to. I disagree. If we are listening to a very high quality speaker that is capable of resolving differences in source components that other speakers cannot, it would seem that this is a very good thing. On the other hand, if two amplifiers sound wonderful driving these speakers and one changes its sound with every change of speaker wire and power cord while the other sounds the same no matter what we do to it, why would we conclude that the "revealing" amplifier is superior? Maybe the other one has a better designed power supply and output section that is more tolerant of load changes and power input. Similarly if we have two preamps or CD players that have equally impressive sound and one sounds different with every change of feet, or object you put on top of it and the other does not, does this make the former the superior piece because it is more "revealing". I think not. The better design should be more resistant to vibration and not have every component in it acting as a microphone. Perhaps this is valued because many reviewers and audiophiles are inveterate tweakers and components that don't respond to these ministrations are simply no fun. I would rather listen to music than fuss about with my system. I think that components should be judged on the basis of how they sound and their ability to resolve the details in the music, not on whether or not they respond to the popular tweaks of the day.

True enough.

I think the general use of "revealing" in our reviews is intended to convey the idea that the component under review is sufficiently resolving to show differences between ancillary components (as opposed to covering up the differences). As you say, a component could be hyper-sensitive to different ancillary components, but we try not to use "revealing" to indicate that. For example, when a speaker seems to be difficult to drive, we don't say it is revealing. We say it is difficult to drive. One standard for distinguishing between compatibility sensitivity and resolving power is to test whether the component reveals things heard previously or dimly. The opposite is also true: a product that tends to make all ancillary equipment sound similar is usually either low resolution or colored in some way.

Reviewers will use some test methods that are not intended to mirror the consumer's usage pattern. For example, we all have test discs that are demanding and therefore useful in revealing certain distortions. But we don't necessarily recommend these discs for your listening. An extreme example of this is the use of sweep sine waves to test for rattles and resonances. I'd be the last person to suggest that you listen to these for pleasure! And, yet, they are very efficient for finding out certain problems.

There is, inevitably, a gray area where compatibility issues could be confused with resolving power. So, the final and fundamental test is whether the resolving power goes hand-in-hand with delivering a sense of the absolute sound. High resolution is really high resolution only if it supports the goal of accurate music reproduction. Compatibility problems tend not to create musically consonant distortions.

I would say the hypothetical cases you describe should not be articulated, if they occurred in the review process, as "this component is revealing" because there is no musical benefit and therefore no real gain in resolution. Rather we should describe what you outline as "sensitivity to ancillaries."
