1. High Fidelity (Hi-Fi)

For a high-fidelity hearing (High Fidelity Hi-Fi), all elements of the chain are essential, from the first link, the source of the signal through the amplifier and the speakers (speakers), to the last, the listening room is often the forgotten element or unknown.

1.1. The signal source and amplification

Until recently, in the analog era, the signal sources were available to all cassettes and vinyl records in such systems has always been a constant struggle to improve quality, increase the average signal to noise ratio and improve response at high frequencies. Today, in the digital age, the signal sources at our disposal are best, with a high signal to noise ratio and a full frequency response in the audio spectrum (CD, DVD, MP3, Blu-ray ..) have no problem.

Amplifiers. Today, virtually all audio equipment comply with the Hi-Fi features in signal to noise ratio (> 90dB) in frequency response and bandwidth (5Hz to 100kHz) and low harmonic distortion of the signal (<0.01%), so that any equipment (decent) is optimal for good hearing.

1.2. Noise barriers

The baffle, the link of contention, in my view, this is the most important chain in the speakers is where you can really see more difference in sound. There are numerous models and types by manufacturer and they all follow the same pattern marked by business objectives (small and light for easy transport and marketing, lack of space) clashing with the acoustic requirements of a room Hi-Fi (large and heavy).

In the market for acoustic screens can be found in all price ranges, sizes and shapes, is a question of needs, space and budget, each mark their goals. Clearly we do not get the same tone with a complete Home Cinema for 100 € with a Hi-Fi speaker alone can cost from 300 € over 1000 €. It is very important to the quality of the speakers and especially the speakers.

We put the best amplifiers and a perfect signal with a mediocre acoustic screens and the sound is mediocre. We can put a normal amp with a good noise barriers and sound will be excellent.
