I don't believe in accuracy other than as an artificial construct when it comes to commercially available music.
I know many devoted music lovers spend a lot of time trying to find the one system that most closely aligns with their subjective experience of accurate sound. They end up on an interminable quest, because the longed-for accuracy is never fully attained.
How many cases of "I've finally found it!" have I heard in person or read in the fora of the sites that I peruse? Twenty? Thirty? Fifty? Hundreds? It's impossible to say, other than "Lots." In a month or a quarter or a year I inevitably read that they've become disillusioned with their "final" system" and have heard or hoped to find the speaker/amp/cable/pre/source/media that will finally take them to accuracy Nirvana.
I have a fair number of systems at home and in a couple of offices. They all sound different. Some have pin point imaging, but little depth. Some have great depth but seem to have a narrow soundstage. Some are like a big wall of sound, while others are like vast, discrete expanses of audio space.
I love them all. I consider all of them "accurate" if they sound the way I like them to sound: they accurately recreate what I want to hear.
I have a fragile idea of what producers, artists, engineers, and mixers want. But as an end product I have little faith that their vision is what I'm getting. It's a facsimile--sometimes a really good facsimile I suppose--but I can only respond by liking it, being indifferent to it, or disliking it. "It" is the product that is as close to or far from what was intended when the artist conceived the music. Sometimes that conception is literally impossible to get in a finished product.
When I hear a cymbal that sounds right, it's a recollection of hearing a cymbal in high school band, of the garage band I played in, the thrashing of Ian Paice at the multiple Deep Purple Concerts I attended, and hearing the Cleveland Symphony at Severance Hall when I was in grad school... or maybe my last hearing of the Long Beach Pops a week ago. Nevertheless, if the recorded cymbal triggers a sense of genuineness, then it sounds accurate based on my experience.
Naturally, I would not care if any of the rest of you thought it was accurate. You're simply ignorant of my experience with cymbals, as I am of yours.
As for "dancing notes," there are times I find this with every system I have, but certainly some more than others. I think it has as much to do with speaker placement and room acoustics as anything else, but definitely some speakers make it easier than others, and, yes, I've heard lots of speakers that just couldn't do it no matter what. It's a combo of soundstage depth and width, perceived accuracy (the subjective kind) and presence. What's presence? It seems like the artist is right there.
I agree that price is not the determining factor. If you get a pretty good speaker that is placed right and has the room treated even in a pedestrian way, there will be more "dancing notes" IME than a great speaker in the wrong place with no attempt at taming the room.
Bottom line: by not pursuing the ephemera called accuracy, I've found many systems from cheap to expensive that give me all the subjective accuracy I need when I need it. Yes, I'm a lucky bastige; I realize that. But it really comes down to what makes you happy, and I think happiness is getting the sound that you like that reinforces your sense of accuracy based on your subjective experience. That's a heck of a lot more attainable than trying to figure out what someone else intended.
At least that's my story, and I'm sticking to it.
