Audio frequency amplifiers are used to convert and improve electrical vibrations in the frequency range perceived by the human ear. Normally, people hear from 20 to 20,000 Hz, upper-class ultrasound devices have a range of 0-200,000 Hz. Over the past decades, the sound reproduction format has changed dramatically from analog to digital, but the need for amplifiers has not disappeared.
We decided to make a top, including the Best Amplifiers For Home 2021. To understand the nuances of work and the capabilities of modern ultrasonic scanning, we took the help of a specialist in acoustic systems, a consultants.
To understand which sound amplifier is best for home use, it is important to consider certain selection criteria and technical specifications, which we will discuss below.

How to choose Best amplifier for the home
Before choosing a sound amplifier, you should familiarize yourself with important technical characteristics that affect the quality of playback. UZCh technically consists of two units – a preamplifier and a power amplifier, which can be independent devices (but it is better to use them in tandem).
Choosing a good amplifier for installing home acoustics is based on the requirements for the hardware and user expectations.
We have compiled a short list of criteria for dual-channel music amplifiers, with built-in power supplies:
- Type . Tube, semiconductor (transistor), integrated, hybrid. The first are considered the most high-quality and audiophile. They are the most expensive. In most cases, the other three are great for the home, due to the affordable price.
- The sensitivity and resistance at the input set the minimum values at which the device can receive and transmit a signal.
- The frequency range for powerful ultrasonic scanning is from 0 to 200,000 Hz. The human ear perceives of them 20-20000 Hz.
- The signal-to-noise ratio indicates the power of the useful sound. The average is 100–120 dB.
- A phono stage is needed to synchronize the source signals, for example, a vinyl player, and an ultrasonic amplifier. Distinguish type MM (moving magnet) – the head with moving magnets, and MS (moving coil) – with moving coils.
- Harmonic coefficient (non-linear distortion) is the percentage of the sum of the introduced signals to the main one. From 0.000025 to 3%, from a slight loss of transparency of sound to the appearance of wheezing, hissing, and a change in timbre.
- Damping . Suppression of excessive vibrations of a dynamic system. The coefficient is calculated as the ratio of the resistance of the acoustics to the amplifier (minimum 5, maximum 5000). The higher the value, the better the sound.
- A digital-to-analog converter turns a binary (digital) code into an electrical (analog) signal that the human ear “hears”.
- Connectors . Usually UZCH equipped with analog and digital ports. A bonus goes – USB and Bluetooth-receiver.
- Power consumption reports how much energy the device can “eat” during its operation. The parameter is relevant for those who save on electricity.
- Additional, but not required options – display, wireless interfaces, remote control.
- The best manufacturers . There is no definite answer to this question, as companies produce various lines, from modest budget to luxury models. Reliable brands are McIntosh, Yamaha, Parasound.
For clarity, the characteristics of the compared models of the rating of Hi Fi amplifiers are summarized in the table.
