Why do audio systems not produce real sounding music?

Because they are not pure audio signal conduits.

What is Hi Fi audio?

Audio is capturing and reproducing sound with 3 main elements of vibration, waves and signal; acoustical, mechanical and electrical.

What is an audio signal conduit?

We refer to the path of the audio signal as the "audio chain".

I love this. I think it's a great first line for the introductory page on the site.

The electrical, acoustical, mechanical part I think we should leave until after each of those individual concepts has been discussed and the reader has developed an understanding of why they are important and what each of them is doing to the sound of his/her system.

I think the thing to do is immediately follow this with a discussion of WHAT is contaminating/degrading the sound. Probably electrical first?

What is an audio conduit made of?

Typically we think of the conduit as being anything physical that carries the audio signal. wire, resistors, capacitors, inductors, transistors and so on. In reality an audio conduit is not only the materials in the parts that carry the signal but also anything that effects the signal or part as it vibrates.

Are vibrations good or bad?

Everything vibrates! Energy is vibration, and any part of an audio conduit relies on vibration to perform. Good vibrations are called in-tune and bad vibrations are called distortion. In audio terms when something is in-tune it means you can hear the whole, when not in-tune the whole is not being represented.

What are the 3 parts to any audio system?

Electrical energy

Mechanical energy

Acoustical energy

What do these 3 parts have in common?

Vibration

What is Vibration?

An oscillation or repetitive motion of energy around an equilibrium point

Do vibrations at a molecular level have a shape?

Yes, spherical

Is an equilibrium point fixed (not moving) ?

No, everything is always in motion

What makes an equilibrium point stable?

Balance

What is balance?

Harmony amoung forces

What is harmony?

A state in which various parts form a satisfying and harmonious whole and nothing is out of proportion

What is it called when something is out of proportion?

Distortion

How do you keep harmony since everything is in motion?

By tuning in the physical properties of the equilibrium point.
