Agree or disagree with the following statement.


Trying to get some input on an issue that a few of us are debating.

Statement:

If you have never listened to any particular component, you can't have an opinion on how it sounds.

Answer:

I don't agree with that. Measurements provide a fairly good indication of how something will sound. That's the beauty of science -- it's not necessary to have first hand experience to make reasonable judgments. You likely disagree and that could be a difference in our background and education."

So, the issue at hand is, can tell how a component sounds without listening to it, and just go on specs? Or, do you have to listen to it, as well, because the specs don't tell the whole story?

Being rather partial to my money and not enamored of do-overs, I insist on an audition before buying. That said, much can be inferred from specifications, and they are the tools I use to determine what to audition.
+1. As I've said in more than a few threads here in the past, the main usefulness of specs and measurements is in identifying and **ruling out** candidates that would be poor matches with other components in the system (e.g., impedance incompatibilities, mismatches of gains, sensitivities, power capability, etc.), or with the listener's requirements (e.g., peak volume capability, physical characteristics, perhaps deep bass extension, etc). But not in selecting among candidates which make that cut, where listening is essential.

By doing that preliminary screening based on specs and measurements, the randomness of the selection process is decreased considerably, together with the likelihood of expensive mistakes.

A second major usefulness of specs and measurements is in diagnosing problems or sonic issues that may arise or become apparent in a system that has already been assembled.

It is also sometimes possible, btw, to rule out candidates from consideration on the basis that some of their specs are simply TOO GOOD. A classic example being THD numbers that are near-infinitesimal fractions of 1%, which is often indicative of heavy-handed application of feedback, resulting in TIM distortion and excessive amounts of the most objectionable kinds of harmonic distortion. Or specs that are so good that they may be indicative of misplaced design priorities, and compromises in other aspects of the design.

As evidence of these usefulnesses of specs and measurements, I couldn't begin to count the number of threads here in which I and many others have found it useful and necessary to refer to the measurements John Atkinson provides in Stereophile.

Just to clarify, the underlying debate is that some people claim that they can look at a spec sheet, and determine how a component will sound, without listening to it. Not that specs can't be of good use in making a selection, just that they can be used as the sole purpose for judging sound quality. For me personally, I can't do that. I have to listen or I can't say how it will sound. Others claim they can, so I'm thinking maybe some people have the ability, or they can somehow learn to read a spec sheet in a way that tells the whole story.
Thanks for the clarification, ZD. I know that in most situations I for one would not be able to predict with any kind of precision or certainty how a component will sound, based on specs and measurements. And I would feel highly confident that the same holds true for the vast majority of other experienced audiophiles.

Totally agree with Al on this one, and for those that rely heavily on specs,
here's some for you,

IMHO, the above will tell you just as much as a spec sheet with regard to how a component will sound assuming there is no measurement that raises a red flag.
Al, absolutely agree but I would even question power specifications. Assuming that they follow any standard (like FCC power) it is only useful if one listens to sinewaves. Average music power is only few percent of maximum power. It is possible that one amp will have 200W rated FCC power but small headroom while the other listed at 100W average has huge headroom allowing to play music much louder. Load characteristic is also important. How particular amp behaves with given speaker (complex load). How much current it can deliver etc.
Is it soft clipping amplifier or the one producing tons of nasty higher order odd harmonics. If sound is related to specifications at all it would be inversely proportional.
