A Digital Analog Converter is a device that sits between a digital source and the amplifier or even in the same device with an amp, to convert to analog to produce audible sound.

The role of the DAC is therefore crucial in the music reconstruction chain and it is advisable to choose carefully the DAC that you are going to use in your dematerialized music chain.

Each DAC has its limits in terms of sampling frequency and resolution: an entry-level DAC will be limited to frequencies in 16bits and 44khz, while mid-range or even high-end DACs will allow you to read files in 24bits 88khz / 96khz or 192khz.

A good DAC will reproduce the sound spectrum better and in a more faithful, more defined way, you can better hear the details, the spatialization of the instruments, and the result is a dynamic and sometimes a very superior emotion.


The Dac has two was of connection to the source

Toslink or Coax: can be connected between any compatible device (including with a computer) but is more restrictive in terms of power supply and sampling rates, the Toslink standard being limited to 24/96.

Role and operation of an amplifier

An audio amplifier is an electronic element that will increase the intensity of an electrical audio signal to transmit it to a speaker. The latter will then transform the electrical energy of the amplifier by sound waves.
