Does 'Accuracy' Matter or exist ?


In the realms of audiophilia the word 'accuracy' is much-used. The word is problematical for me.

In optics there was once coined a descriptor known as the ' wobbly stack', signifying a number of inter-dependent variables, and I believe the term has meaning to us audiophiles.

The first wobble is the recording, obviously. How to record (there are many microphones to choose from...), what kind of room to record in (an anechoic recording studio, live environment etc), where to place the chosen microphones, how to equalize the sound,
and, without doubt, the mindsets of all involved. This is a shaky beginning. And the ears and preferences of the engineers/artists involved, and of course the equipment used to monitor the sound: these too exert a powerful front-end influence. Next comes the
mixing (possibly using a different set of speakers to monitor), again (and of course) using personal preferences to make the final adjustments. My thesis would be that many of these 'adjustments' (EQ, reverb etc) again exert a powerful influence.

Maybe not the best start for 'accuracy', but certainly all under the heading of The Creative Process....

And then the playback equipment we all have and love.....turntables, arms, cartridges, digital devices, cables, and last but never least, speakers. Most, if not all, of these pieces of equipment have a specific sonic signature, regardless of the manufacturers' claims for the Absolute Sound. Each and every choice we make is dictated by what? Four things (excluding price): our own audio preferences, our already-existing equipment, most-importantly, our favorite recordings (wobble, wobble), and perhaps aesthetics.

Things are getting pretty arbitrary by this point. The stack of variables is teetering.

And let us not forget about the room we listen in, and the signature this imposes on everything (for as long as we keep the room...)

Is there any doubt why there's so much choice in playback equipment? To read reports and opinions on equipment can leave one in a state of stupefaction; so much that is available promises 'accuracy' - and yet sounds unique?

Out there is a veritable minefield of differing recordings. I have long since come to the conclusion
that some recordings favor specific playback equipment - at least it seems so to me. The best we can do is soldier on, dealing
with this wobby stack of variables, occasionally changing a bit here and there as our tastes change (and, as our Significant Others know, how we suffer.....).

Regardless, I wouldn't change a thing - apart from avoiding the 'accuracy' word. I'm not sure if it means very much to me any more.
I've enjoyed every one of the (many, many) systems I've ever had: for each one there have been some recordings that have stood out as being
simply Very Special, and these have lodged deep in the old memory banks.

But I wonder how many of them have been Accurate........

I want the instruments to sound the way I think they're supposed to sound, e.g., strings, woodwinds, brass, keyboards, percussion, vocals, etc. This meets my definition of accuracy.
From Wikipedia:

"In the fields of science, engineering, industry and statistics, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to its actual (true) value.

If this were a pro-audio forum where there was some aspect of engineering and science to what the participants were being relied upon to accomplish, this might be something to consider. But this is a forum of end-users - those who assemble equipment in order to enjoy the music. Let me say that again, as it has been said so many times in this thread: The goal here is TO ENJOY THE MUSIC. You can use whatever criteria fits your own personal take on it, and if your own interpretation of what "accuracy" means to you fits into that personal interpretation, then so be it. It does not matter and you will never find any remotely universal agreement on any of it.

100% accuracy means perfection. 95% accuracy does not.

Accuracy has nothing whatsoever to do with perfection. Accuracy is a notion that is objective, Perfection is judgment which is entirely subjective and will not be universal ("perfect" beauty for a westerner may be a polar opposite for someone from a tribe in Africa or from an Asian or Persian culture). What is a perfect movie or perfect book? Perfect music? Perfect clothing? Perfect food? Any answers to those are simply an opinion and nothing more. If we were to believe MrTennis and Abucktwoeighty, then a perfect movie is the one that is 100% accurate....perfect beauty is 100% accurate...a perfect musical performance is one that is 100% accurate. Accuracy is essentially true or false and nothing more. It has little to do with how human beings perceive and interpret the world around them and does require a universal agreement as to what defines what is true and what is false in any application of the word. In absence of that universal agreement you will never have "accuracy". You will NEVER find such a universal agreement on any notion of "perfection" or personal tastes. It is not remotely the same.
Of course accuracy exists and it is somewhat important. Without a standard of accuracy we would have subjective chaos. Without a standard of accuracy someone could assert that their 8-track, Crown amp and Bose 901s (Series IV) sounded better and was more pleasurable than anything they heard a the last CES and the statement would be unassailable.

At a practical gauging an individual component's accuracy is relatively difficult, but doing the same for a system/room is much easier. Contact a mastering studio and arrange to attend an actual mastering session. Listen to the final mix. Purchase a copy of the recording. Does the recording played back in your room on your system sound like the recording when played in the mastering room? If it sounds substantially the same, then your system/room is fairly accurate, at least to your ears.

Additionally, if accuracy wasn't at least somewhat important, then why have high costs, high end systems? If the only measure is enjoyment/involvement, then is sipping a quality bourbon while sitting next to a super sexy woman and listening to a table radio a more musically enjoyable event than listening alone in the dark to some $100k+ audiophile system? Which is more memorable?

All that ridiculous jumping through hoops and you may still discover that you actually prefer to listen to that very recording on a system that makes it sound different than it did in the mastering room (ie "inaccurate"). It means nothing to the end user unless you make it mean something to you. It is neither here nor there.

Furthermore what makes one prefer their system over your hypothetical, deluxe Crown Amp/Bose/8track may have everything or nothing to do with accuracy. Ultimately it is quite simply a personal preference and nothing more, and the individual who actually thought the deluxe system may actually prefer it for whatever personal reasons.

There are no "practical" reasons for gauging components for the end user (perhaps for engineers). The best you can do is share your own experiences and preferences, and I think in some ways that can be generous, but ultimately a point of departure for others to form their own opinions - in the end it doesn't matter - its what your personal preference happens to be.

I've had a few moments from my youth with a cheap car stereo playing music, and a beautiful woman in the backseat (and front seat) of a car on a moonlit night parked alongside a country road a million miles from nowhere... I can tell you those moments are plenty memorable, and were profoundly enjoyable. I can think of many other moments of profound enjoyment of music that are plenty memorable where no expensive components were involved that I remember to this day. I also have memories that do involve expensive components. Ultimately it was the music and all kinds of other things about the moment that made the difference. It had nothing at all to do with any notion of "accuracy" or "perfection".

Anytime someone tells others you haven't lived until you've listened to music on a $x(insert lots of zeroes) system, run, don't walk, in the opposite direction. Buying into such BS is a recipe for unhappiness. There will always be something better, the grass will always be greener over yonder, that is until you drink the grape Kool Aid and empty your wallet and bank account, and agree, in spite of your own preferences, that there is some objective realization of a perfect anything.
If I were a psychiatrist, I could get in on this; but since I'm not, I had better stay out, or I will need a psychiatrist.
