Is it better to use digital power amplifier or traditional power amplifier for floor speakers?

Digital power amplifier is better, but the price is higher. At present, the domestic digital power amplifier technology is immature and the import price is too high. Traditional analog power amplifier can be used for home floor speakers.

Digital power amplifier is a kind of amplifier with small distortion, low noise and large dynamic range, which is incomparable to traditional power amplifier in cold and warm sound quality, resolution, quiet background and low frequency impact.

The basic circuit of digital power amplifier is a long-standing class D amplifier (called class D amplifier in China). Previously, due to the price and technical reasons, this amplifier circuit was only used in laboratories or high-priced test instruments. With the development of technology in recent years, the components of digital power amplifier are integrated into one or two chips, and the price is also falling.

Theoretically, the efficiency of class D amplifier can reach 100%. However, so far, the ideal switching element has not been found, and there will inevitably be some power loss. If the devices used are poor, the loss will be even greater. But in any case, its amplification efficiency is above 90%.
