Which and how to choose an amplifier?

For starters we cannot forget the importance of technical performance. But do not forget that the power must be adapted and comfortable to the size of your room.

The bandwidth of the amplifiers is almost always large, as is the distortion rate, which is practically imperceptible for transistor models. The rise time, on the other hand, is more variable from one model to another; A very high rise time guarantees a good musicality because it restores well the transients, essential in the musical signal.

The presence of an integrated DAC and its technical characteristics, including the types of files it supports (16-bit / 48-kHz, 24-bit / 192-kHz) are crucial for all digital audio enthusiasts. It is necessary to study the connections necessary to take advantage of the digital audio sources: USB for a computer, network connection for a DLNA server or NAS connected to the local network, S/PDIF optical or coaxial inputs.

A DLNA Hi-Fi amplifier lets you listen the music online from a multitude of Internet services, as well as audio files shared on a home network or streamed wirelessly from a smartphone or tablet iOS and Android for example.

Keep in mind, the amplifiers are the real hotspot of an audio installation because it is the amplifier that determine the quality of the power used by the speaker.
