Integrated, pre and power amplifiers
An integrated amplifier combines a preamp, which selects sources and sets volume, with a power amplifier that drives the speakers. It is the most common choice. Separate pre and power amplifiers split these jobs for more flexibility and upgrade options, at the cost of more boxes and cables.
Power and matching
Output power is quoted in watts per channel into a given impedance, usually 8 or 4 ohms. Speaker sensitivity matters as much as amplifier power: efficient speakers play loud with modest power, while less efficient speakers or large rooms need more. Check that the amplifier supports your speakers' impedance.
Inputs
Count your sources. A phono input lets you connect a turntable directly, usually for MM cartridges and sometimes MC. Digital inputs with a built-in DAC accept optical and coaxial from a TV or streamer, and HDMI ARC makes TV control easier. USB lets you play from a computer.
Features
Tone controls and a balance control help adapt the sound to your room. A headphone output is useful for private listening. Some amplifiers include streaming and Bluetooth, turning them into a compact system. Pre-outs let you add a power amplifier or subwoofer later. Some amplifiers also offer a home cinema bypass, which lets them sit in a surround setup. Choose the inputs and features you will use, rather than the longest list.

Frequently asked questions
What is an integrated amplifier?
An amplifier that combines source switching, volume control and power amplification in one unit, ready to connect passive speakers.
How many watts do I need for my speakers?
It depends on speaker sensitivity and room size. Check the power range the speaker maker recommends and choose an amplifier comfortably within it.
Can I connect active speakers to an amplifier?
Not to its speaker outputs. Active speakers connect to a line or pre-out from the amplifier or directly to a source.
Do I need a separate DAC with my amplifier?
Only if the amplifier has no digital inputs, or you want an upgrade. Many integrated amplifiers include a DAC.
Are valve amplifiers better than transistor amplifiers?
Neither is better in general. Valve amplifiers have a character many people enjoy and usually less power; transistor amplifiers are often more powerful and need less maintenance.
Which speaker cables should I use?
Use cables thick enough for the length of the run, with good connections at both ends. Longer runs and lower-impedance speakers benefit from thicker cable.
