Deciding which type is right for you can be tough when shopping for a new amplifier. For example, do you need an integrated amplifier, or will a power amplifier suffice? In this article, we’ll explore the differences between these two types of amplifiers and help you decide which one is best for your needs.


The amplifier is a critical component of a stereo system, responsible for amplifying the signals from the sources connected to the amplifier, switching the connected sources, adjusting the volume, and transmitting the amplified signal to the speakers for playback. Depending on the level and design, all amplifiers can be divided into single-block (integrated), two-block (combination of the preamplifier and power amplifier), and three-block (combination of preliminary and two monoblock amplifiers). Here we will talk about the first two types.

Integrated Amplifier

It is an amplifier with all functional blocks located in one housing, including all controls, preamplifier parts, and power amplifiers.

Transistor, tube, and hybrid integrated amplifiers are distinguished depending on the amplifying elements used, including transistors and lamps. Integrated amplifiers come with a built-in power supply, and with a remote one, they are divided into classes “A,” “B,” “AB,” and “D” they can be analog or digital. Integrated amplifiers are the most affordable and easy to connect.


  • All necessary functional blocks are in one case.
  • Affordable and easy to connect.
  • It can be used in a small room.
  • High-quality sound.


  • The overall quality of the sound depends on the selected amplifier module.
  • It isn’t easy to repair or replace a failed module.
  • Not as powerful as a power amplifier.
  • It can’t be customized.
  • Limited power.

Power Amplifier

It is a part of a complete amplifier, made in a separate case. It is responsible for detecting the signal from the intended amplifier and transmitting it to the speakers to the limit.

The main amplifier increases the signal’s power so connected speakers can play it loudly. Power amplifiers, as a rule, do not have any settings, including no volume and power control, since all settings are made with the power of the preamp connected to the amplifier. Power amplifiers also come in both transistors and tubes.


  • You can choose the sound you want by choosing the proper preamp.
  • Easier to repair or replace a failed module.
  • Simple design.
  • Provides unique customization options.
  • It can be used with any speaker.
  • Provides high-frequency response and excellent sound quality.


  • More expensive.
  • Requires an additional connection.
  • Without a preamplifier, it is impossible to control the sound.


Integrated amplifier vs power amplifier – monoblock instrument against several devices that amplify the sound. Both of them have their pros and cons. The best choice for you will depend on your needs and preferences. If you’re not sure which one to choose, consult with a qualified audio/video specialist.
