Elements of influence on sound

It is in fact a long way to go untill everything is recorded and on CD.
Is it a faithful reproduction of the natural sound of these guitars?
I think not as there are too many circumstances that are of influence
on the sound result but at least you can make an attempt.

The classical guitar CD's are getting better and better but the problem
stays that a player mostly is not able to translate his wishes into technical
moves as frequency cutting or boosting. adding reverb and/or delay.
The use of compression that affects the tone of the guitar to my believe.

- Who is playing.
- The (exact) tuning of the instruments
- How big is the room in which the recording took place.
- Difficult pieces are harder to play with a great tone than easy
  pieces.
- Placing of the microphones and use of big or small membraam mics.
- Sometimes the humidity and temperature of the day affects the result.
- Some specific guitars are more suitable for a certain kind of music.
- Condition of the nails of a player: thick nails tend to give more thickness
   in tone than thinner nails that on their turn enhance the higher frequencies.
- The quality of the equipment on which it is played.
- The specific quality of the ears regarding frequencies: Hearing loss.
