Please Educate Me


If I can’t find the answer here, I won’t find it anywhere. 

Something I’ve wondered about for a long time: The whole world is digital. Some huge percentage of our lives consists of ones and zeros. 

And with the exception of hi-fi, I don’t know of a single instance in which all of this digitalia isn’t yes/no, black/white, it works or it doesn’t. No one says, “Man, Microsoft Word works great on this machine,” or “The reds in that copy of Grand Theft Auto are a tad bright.” The very nature of digital information precludes such questions. 

Not so when it comes to hi-fi. I’m extremely skeptical about much that goes on in high end audio but I’ve obviously heard the difference among digital sources. Just because something is on CD or 92/156 FLAC doesn’t mean that it’s going to sound the same on different players or streamers. 

Conceptually, logically, I don’t know why it doesn’t. I know about audiophile-type concerns like timing and flutter. But those don’t get to the underlying science of my question. 

I feel like I’m asking about ABCs but I was held back in kindergarten and the computerized world isn’t doing me any favors. Now, if you’ll excuse me, I have some work to do. I’ll be using Photoshop and I’ve got it dialed in just right.

It's a shame that the immediate response to your question was snark, but I'd like to think this is more a reflection of the times rather than our community.  However, just like other forms of social media it pays to consider your words and choose them carefully.  Also like other forms of social media, you shouldn't take it too seriously. 

I think a few of the posters here have hinted at why ones and zeroes in audio are not the same as ones and zeroes in other types of digital files or processes.  Your original post suggested it as well.  You said timing and flutter but I think you meant timing and jitter.  Jitter is errors in timing that cause distortion.  A music file may be ones and zeroes but that is only until you begin to play it back.  What was previously just data now has to be precisely reproduced not just in terms of the sounds those ones and zeroes represent, but accurately in terms of timing as well.  This is not that easy to, at least not well, and is likely what accounts for the biggest differences in the sound quality of one DAC vs another.  Any part of the signal chain that disrupts that timing hurts the quality of the reproduced signal.  Despite variations from human to human, our ability to hear is pretty amazing and when we hear reproduced music, with even very small timing errors we can tell and it doesn't sound as good as it should.  So yes, all the bits and pieces in your reproduction chain matter, disc players, and cables, etc., but I believe that this is the fundamental reason that digital sounds different than analog.  Analog is subject to other kinds of distortion, but that's a different topic. 

One of the ways audio technology has advanced to deal with this issue is sampling rates.  A sampling rate of 192,000 per second is better that a rate of 44,100 times per second because you're dealing with a much smaller slice of time and these slices represent finer gradations of the signal.  As if your picture had more pixels. 

Now imagine a pure sine wave and just one second's worth -divided into 192,000 slices.  Each slice is like a step in the shape of the that wave.  More slices gives you more resolution and a better, more accurate facsimile of that original sound, but you're still chopping up what was once a continuous wave and reassembling it. 
Oh, and now imagine it's not a pure tone, represented by a perfect sine wave but a complex mash up of instruments, voices, hall ambiance, etc.  You get the idea.  Like my father used to say, "timing is everything." 

Music represents a very complex kind of information.  Reproducing it with the hope of making it sound like the real thing is tough.  It's a modern wonder that digital music works at all and that so many of us hardnosed audiophiles are happy with it.  I'm sure there are plenty of folks here who can do a better and more accurate job of explaining this than me.  I struggled with this too, but someone explained digital audio to me this way once and it was the first time I felt like I was getting a handle on it.  I hope this helps to answer your question.  Just for the record I listen to BOTH kinds.  Regular and extra crispy. 

BTW I leave my equipment on all the time unless it's storming or I'm on vacation.  I know it's a waste of energy but it seems like such a small indulgence...
And welcome to the club.  You're not really an audiophile unless you've been attacked in a forum.

@woofman - Hard nosed audiophiles are not happy with digital music. You might say serious audiophiles aren’t, but that would cause a heated argument. 
MS Word remains digital when we see and use it, whereupon music ends up analog.  No digital speakers out there that I'm aware of. If there were, they'd still have to move air, so different materials, masses, enclosures,  room characteristics,  etc, etc, will affect sound.

Sorry for the overly critical and angry replies. There's plenty of good experience and advice here...if you don't mind wading through the flaming trolls.

Remember: There is no spoon. :)
Another county heard from. 

Paul McGowan of PS Audio in conversation with John Atkinson of Stereophile, February 28, 2018. The conversation, which has been edited for readability, is available at https://www.youtube.com/watch?v=O0NUvziOgWQ

Atkinson: . . . Putting a disc on, it's like going back to the last century. [Leaning forward, sly grin.] But there's still something right about the sound of a mechanical disc playing in a mechanical player.

McGowan: It sounds better. It sounds better, so far, than any server we've tried. We're working on a server. And we're going to fix that problem. We think that we may know why the physical disc sounds better. Because on the surface, it makes no sense whatsoever. The bits are the same.

Atkinson: Right, they're the same bits being presented to the DAC.

McGowan: Yup, yup. But that's true only insofar as it's ones or zeros. What's different is the timing of the bits, the noise levels [more engineering stuff].
Paul6001,

I was new here not so long ago too. I liken the experience to being a bride’s guest at a wedding where most of the other guests are the groom’s family - and they drink too much and bicker over dinner and end up having a fist fight in the car park. Like that bride’s guest, it is better to watch, not join in.

On your points - I think there are many engineering choices to be made when processing digital information, especially when making the first capture of analogue sound and also when converting it back. There are loads of engineering choices too when the storage medium is a spinning vinyl disc. We hear replicas of the original sound. It is an illusion. The recording engineers, mastering, encoding, and decoding are choice-maker at every stage. You are hearing their choices when things sound different. 
Your listening - if I was you, I’d put together a headphone system for personal listening. Use Roon to benefit from crossfeed filters. Seems like in your NY apartment you will struggle to have a listening room and a living room in the same space. So don’t try. Headphones for personal listening, and some easy listening omni-directional room-filling, guest-pleasing speakers for social listening.  I’m a fan of back-loaded horns because wherever you and guests  sit in your room everyone gets a lovely listen. 
Now, see you soon in the car park where we can watch some of the old boys take their jackets off and start swinging - and missing.
