The Norman manufacturer of high-end electronics doesn’t take vacations! It was obvious that after the release of the 400 series, Atoll had to offer an intermediate product bridging the gap between the IN200 integrated amplifier and the IN400 integrated amplifier. Well, they have done it!


The Atoll IN300 integrated amplifier adopts a classic look, less striking than its predecessor, while retaining its front panel architecture.

In the center is a window housing a low-consumption OLED display.

On each side, there is a large logic potentiometer: the one on the right manages volume (by rotation) and balance (by pressing), while the one on the left manages source selection (by rotation) and power on/off (by pressing).


On the back, the Atoll IN300 offers five analog inputs, one of which can receive an optional Atoll MM/MC P100 phono card.

There is also a balanced XLR input. This balanced bipolar stage is fully implemented with discrete components.

These inputs are complemented by 2 pre-out outputs, a By-Pass, and an IN/OUT tape.

The IN300 integrated amplifier is also equipped with an excellent DAC: PCM 32 bits – 768kHz! It is accessible via 6 digital inputs: 2 coaxial, 2 optical, and one USB-B. Note that the USB DAC is an XMOS USB: XHRA-2HPA with a program specifically developed for Atoll.

Please note that using the USB input requires downloading a specific driver for Windows computers, but it is not necessary for Mac.

The 6th digital input is via a Bluetooth module integrated into the DAC.

The speaker outputs are of excellent quality. The terminals are specific and machined from copper specially for Atoll.


The internal architecture is impressive!

The Atoll IN300 is completely dual mono. It is powered by two 440 VA toroidal transformers.

Filtering is handled by 12 audio-grade electrolytic capacitors, totaling over 86,000 uf of capacity!

The analog stages receive shielded MKP Mundorf capacitors, and the digital stage receives very high-quality audio MKP Vishay capacitors.

It is also noteworthy that the internal wiring of the speaker outputs is done with high-end speaker cable.


Handling is "physical"... 15 kg in such a small volume is quite impressive! This speaks volumes about the build quality.

Its compact dimensions allow it to be easily placed, so there’s no need for custom furniture. Just make sure it is sturdy.

Its power handling allows it to be paired with even recalcitrant speakers worth 2 or 3 times its price!


We tested it with a monitoring speaker and two very different floor-standing speakers (the French Focal Sopra 3 and the Italian Sonus Faber Olympica V).

After 24 hours on standby and a burn-in period of around twenty hours (minimum), the sound reproduction is clearly based on neutrality and nuance. It exudes an obvious naturalness combined with exemplary speaker control.

Some criticize Atoll for a clear and analytical sound?! This is absolutely not the case with the IN300 integrated amplifier. Sure, it doesn’t have the roundness and presence of an MC 5600, but it gains in finesse and naturalness.

It is not a flattering or demonstrative amplifier. It is intended for true Hi-Fi lovers.

Its versatility is remarkable, with both analog and digital sources. The quality of its DAC opens up unprecedented possibilities in this price range.

The only downside: the possibility of adding the Atoll P100 phono card. Even though it is of good quality, it is clearly not up to the standard of the IN300 and the turntable that would be paired with this superb integrated amplifier. But nothing serious, there are enough excellent phono preamplifiers available to address this issue!

To date, the Atoll IN300 integrated amplifier is certainly one of the best, if not the best integrated amplifier in its range. It offers everything one could expect from a "modern" device in terms of connectivity and possibilities. And all this combined with remarkable musicality and sound reproduction!

Congratulations to Stéphane Dubreuil and his team, our favorite is made in France!

Un superbe intégré

Pas encore rodé et pourtant c'est déjà magique. Très dynamique et clair, il fait chanter mes Sopra n2 et je reprends du plaisir à réécouter mes disques. Bravo Atoll.
