We have reviewed hundreds of stereo amplifiers – for most hi-fi systems, these are the only three you need to consider

Integrated amplifier: Arcam A15.

The stereo amplifier is the beating heart of your hi-fi separates system. At What Hi-Fi?, we have been testing them ever since 1976, and our experienced review team has collectively tested hundreds of integrated amplifiers, priced anywhere from £200 all the way up to £30,000.

You don't have to spend thousands to get a good stereo amplifier, though. In fact, you don't need to spend very much at all to get a truly great integrated amplifier these days.
