The 7 best stereo integrated amplifiers for 2023

In the constantly evolving landscape of hi-fi audio systems, integrated amplifiers bridge the gap between tradition and innovation, embodying the industry’s effort to adapt to new generations of audiophiles while maintaining the highest standards of sonic reproduction.

There’s no doubt that choosing the right stereo integrated amplifier for your hi-fi system is fundamental. It can take the sound’s accuracy and warmth to a whole new level, enhancing the quality of your music collection, be it on vinyl, CD, or streamed from a mobile device.

Below is a list of what I believe are the 2023’s best stereo integrated amps, based both on performance and value for money.

This is part of a two-article series where I discuss the best integrated amps for all budgets, and here you’ll find exclusively mid-range to high-end options. For my take on the best budget integrated amplifiers, check out this piece.

About the author

I’ve been immersed in sound since I learned how to use my parents’ old Aiwa hi-fi system. Over the years, my passion for music has developed into a full-time profession, using cutting-edge equipment to mix and master music but also running workshops on deep listening and the benefits of experiencing music in the best possible way.

How we chose the amplifiers on this list?

The level of complexity of integrated amplifiers has grown considerably as the audiophile world embraces new technologies for streaming audio. As a result, this list includes integrated amplifiers that can satisfy the needs of listeners using both digital and physical media.

I considered amplifiers with a diverse range of power outputs to ensure you’ll find the one that’ll perfectly fit your existing gear and listening area.

Aspects such as connectivity options, multiple inputs and outputs, a built-in DAC (digital-to-analog converter), and a phono stage are also things I considered while compiling the list.

Finally, you probably know that some stereo amplifiers focus on accuracy over warmth, or vice versa. In this list, I included both types of amplifiers, so regardless of your taste, you should be able to find one that’ll enhance the quality of your collection.

These are the best stereo integrated amplifiers to buy:
