High Fidelity Sistems
It can be defined as High Fidelity the ability to play the full spectrum from 20 Hz to 20 kHz (the frequencies audible to human ears, but this varies from person to person)
These types of systems, curiously, are widely used, but there are large differences between the products of this group.
Basic Level System:
We can find these products anywhere on the street, at home, etc. .. The products that fall into this classification, we can see the MP3 players, Walkmans, the Diskma, radios. This is the most basic level of quality and the price is very accessible, going from 10 to 1000 €.
It is important to note that such systems can not hear a perfect sound quality, but for those who are not too demanding ...
In another more advanced group, we found the audio equipment that some people have at home (radios, stereos, turntables)
In this group we find superior technologies, ranging from 1000 € to 20000 €.
These types of systems are little known to most people and are equipped with amplifiers that have the function to attenuate or emphasize certain frequency bands, or may even exceed the range of audible frequencies, for the most expensive are computers in theory are able to recreate in a room the sound of a symphony orchestra or a jazz band, with no differences between the original sounds, but are very expensive, between € 20,000 and € 100,000 ¡¡¡¡¡¡¡ declare that the prices here are used for indicative purpose.
