You say what ?

Genetic variation, brain, and intelligence differences

There is enough variation in brain neuronal structure to make large differences in music processing or as we might call it - "musical intelligence."

@bolong - what you say may well be true, but the basis for determining what sounds realistic to each of us comes from the same sources that create sound waves, which pass through air and into our ears. We may well hear differently, but what we identify as realism is of the same origin. The equipment that reproduces recorded sound waves are thus equally judged from their approximation to those origins. So there is indeed a basis for comparisons we can all share.

There is some basis, but it is not total.

I was discussing this subject with a friend of mine, and we also interjected into the topic the notion that exogenous chemicals such as alcohol and THC when added to the neuronal capacitors and resistors produced a "tube" sound with holographic realism whereas stimulants produce a solid state sound. Some of these chemicals might also be likened to "designer fuses" and the effects of different cabling. LOL

Nice change of pace @bolong . This is interesting stuff to me and I enjoy expanding my knowledge of how things work. A couple of observations:

The neuron issue relates to an interesting idea about analog vs. digital. Most audiophiles (I think) believe that our brains and nervous systems work on an analog model. Our nervous system, however, much more closely resembles a digital network. Neurons fire a quick burst of energy and then go back to a neutral state. This is significant because many in our hobby believe that digital is somehow unnatural and therefore inferior to analog.

Many of us have an American idea of equality that we project onto our biology. We think that we have all been gifted with the same basic intelligence and our differences can be explained by education and upbringing. The Molecular Psychiatry article addresses this misconception. In reality, we are highly variable individuals and just like the fact that a few of us can run a marathon in 4 hours, some of us have brains that are wired better or worse for different functions.

We have all probably met or known someone who simply cannot process music. Their brains don't perceive the rhythm and melody that we love so dearly. Their internal wiring is different than ours.

I've been to a few audio shows and what fascinates me about this hobby is that two audiophiles can reach a completely different judgement on a particular sound. In one instance where I thought the system sounded harsh, bright, and unpleasant, the guy literaly sitting next to me loved it and said that he felt it was the best sound at the show. What's happening with all of those little neurons has a major effect on how we perceive reality.
