Maybe being discerning isn't that good for us?


A topic I touch on now and then, I think about what the average person hears, what I hear, and what it means to be discerning. What good is it for us, our community, and the industry?

I’ll touch on a couple of clear examples. I was at a mass DAC shoot out and spoke with one of the few ladies there. To paraphrase her, she said this:

Only with DACs made in the the last few years can I listen to digital music without getting a headache.

I never had that problem, but we both experienced a significant improvement in sound quality at about the same time. Lets take her statement as 100% true for this argument.

On the other hand, I am completely insensitive to absolute phase issues which some claim to be. I’m also VERY sensitive to room acoustics, which many fellow audiophiles can completely ignore.

Lets assume the following:

  • The lady really did get headaches due to some issue with older DACs
  • There really are people very sensitive to absolute phase.

I’ve also found the concept of machine learning, and neural networks in particular truly fascinating. In areas of medical imaging, in specific areas such as breast cancer detection, neural networks can be more accurate than trained pathologists. In the case of detecting early cancer, discernment has an obvious advantage: More accuracy equals fewer unnecessary procedures, and longer lives, with less cost. Outstanding!!

Now what if, like the trained neural networks, I could teach myself to be sensitive to absolute phase? This is really an analog for a lot of other things like room acoustics, cables, capacitors, frequency response, etc, but lets stick to this.

Am I better off? Did I not in fact just go down a rabbit hole which will cause me more grief and suffering? Was I not better before I could tell positive vs. negative recording polarity?

How do you, fellow a’gonner stop yourself, or choose which rabbit holes to go through? Ever wonder if you went down one too many and have to step back?

I have to say though, the GIK Acoustics are panels are effective, pretty and high value. :)

And yes, room acoustics is something I have always been sensitive to. Not just for music. Spending a long time in an office with live sheet rock is exhausting.
FTR: You don't have to spend a lot of money to have good room acoustics, but it doesn't hurt. :)

Certain folks smell, taste differently


It's true, I dislike the taste of vegetarians personally. I can't get past the sense of eating fat Brussels sprouts.

Hook up one speaker out of phase and listen to what happens.


There is a misunderstanding. I am more sensitive to speakers being wired out of phase to each other than a lot of other people.

What I am not sensitive to is the phase of the recording, or as some call it, absolute phase.
Erik, the Turtles first lp was recorded with all voices to the left and all the instruments in the right channel.


I believe you.  My point was, it wasn't recorded like this, it was cut like this. :) They probably originally recorded it intending to go to mono.  Stereo hit and they didn't have the mixers to do anything else.
She noted that studies show very hightened listening capability among those who grow up in highly stressful households, because you learn to listen veeerrry carefully for nuance in tone before someone explodes.

I do this to, for the same reasons, in my case, the advice was that I was too sensitive to get the message. That my sensitivity to tone prevented me from hearing the words too. I find that this varies for me depending on how stressed I am, and have to be extra careful when stressed or tired that I'm not misunderstanding.

A good analog, in the positive and negative sense, of us hearing audio equipment. Listening to the foibles may make it hard for us to hear the emotion in the notes.
Absolute phase is interesting. To me it is stunningly obvious, and it boggles my mind to think that others cannot hear it.


I can’t hear it. At all. From experts I've read, it's all about how the ear mechanically works. It is of course possible some people are sensitive to it, the brain and neural learning are capable of detecting non-obvious signals and using them in ways we don't fully understand.

But ... from all the reading, I'm in the majority.
I know some recordings were originally meant to be multi-track mono.

That is, they recorded to multiple tracks, but meant to release the final product in mono. Then stereo came and labels started doing "cheap" stereo recordings by going back to existing recordings and using one channel for a voice, another for an instrument.

I'm not sure how prevalent this was, but I think there's at least one Beatles album like this.
