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........

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?
Everybody is entitled to their own opinion, but not their own facts. Accuracy is about facts, liking what you hear is about opinions.

The problems with the 8-track, Crown, Bose example I cited earlier isn't that I like it better, but that I say it is better and without a standard of accuracy you couldn't argue that my statement was false.

Another problem I have with the radical subjectivist, if it feels good - it is good school of audio is that it denies individual achievement. As with any task some people are better than others at putting together audio systems. It's probably a bell shaped curved with a small percentage of people who truly excel at the task. But if all that matters is how good you feel, then in effect you're denying the bell shape and cramming everyone into a homogeneous blob. Without some standard of accuracy high end audio could not exist. At one point the hobby was actually call high fidelity, as in fidelity to a sound source. Have we really completely lost our way?
My point is that there is no single Carnegie Hall or Ella Fitzgerald sound. Depending on how and the conditions of the recording sessions any number of Carnegie Halls could result. When you play a recording made there, how do you know which version of Carnegie is on the recording? I don't think you can say. That was my earlier point about having to be at the mastering session to be able to gauge what a recording is supposed to sound like.

I find the standard of live music as a reference to be useful, but as commonly applied by audiophiles it virtually ignores the recording process which is at least as important as anything on the reproduction side.
Charles1dad, it's not just that he has nice equipment, but his room is carefully arranged not to significantly color the speaker output. He even has measurements to back that up. A very high quality studio monitor in a well designed/setup room will give you an relatively accurate sound. And by accurate I simple mean reasonably low distortion, a smooth wide range frequency response curve, wide range dynamics and low resonances. It's a relative description, not an absolute term. Systems that meet these goals tend to be accurate to their source material (to the extent that that even can be judged). I would suspect that your system qualifies as accurate too.
Is that Ella's voice in 1952 singing into an RCA ribbon mic or Ella in 1964 using a Neumann condenser? Is that the sound of Carnegie Hall from the the first level under the balcony or from the second mezzanine? Are all the seats filled? Is it winter or summer? All of these scenarios will sound different when recorded. If you tune you system/room so sharply that only one situation sounds like Ella or Carnegie, then you have strayed and lost your way.
The main hall at Carnegie seats 2,800 people. Am I to believe that you think whether the hall is empty or full of concert goers has only a subtle impact on the sound within the hall? If you do believe such, then I respectfully disagree. The presence of concert-goers will effect hall volume levels and the tonality of reflected sound. It's not a subtle effect.

I am not dismissing the relevance of a standard, instead I'm pointing out a severe limitation of that standard as commonly used.
The ref has stopped the fight, the Hwyman is barely on his feet clinging to the ropes and clearly can no longer defend himself. The Amphibianman's team has run into the ring and hoisted him upon their shoulders in a victory stance. #61 is being helped out of the ring his face a bloody pulp and his legs wobbly, but it appears he's trying to shout something at the winner. "You never knocked me down, Frog. Never knocked me down!"
