Atoll IN200 Evolution: The Next-Generation Integrated Amplifier
The Atoll IN200 Evolution integrated amplifier boasts a sleek and refined design. Its 8 mm thick brushed aluminum front panel is adorned with two large rotary knobs flanking a low-consumption white OLED display. The smooth shapes of the knobs give the device a distinguished aesthetic. The 1.5 mm thick metal chassis ensures optimal rigidity, preventing any mechanical vibration. The perforated top cover allows for efficient heat dissipation.
Dual Mono Architecture
The IN200 Evolution features a dual mono design, with two 340 VA toroidal transformers separately powering the left and right audio stages. This architecture ensures perfect channel separation, greatly enhancing soundstage and dynamics. The differential input stages with bipolar transistors and the output stages with MOS-FET transistors offer high linearity and low distortion.
Carefully Selected High-End Components
Atoll has equipped the IN200 Evolution with handpicked components for optimal musical performance. The 59220 µF ESR filtering capacitors, custom-made, provide substantial energy reserves. The audio stages use shielded Mundorf MKP capacitors, identical to those in the IN300, for improved signal-to-noise ratio and great musicality. Volume management is handled by a precision attenuator per channel, derived from the IN300, ensuring excellent stereo separation.
Optimized Power Supply and Low Consumption
In addition to the two 340 VA toroidal transformers dedicated to the audio stages, the IN200 Evolution features a 10 VA digital transformer for the display and logic circuits. High-precision current sources based on transistors and LEDs ensure perfect stability of the idle currents. An eco mode allows for standby consumption below 0.5 W. The preheating mode, with a configurable standby time, optimizes performance from the moment it is powered on.
Comprehensive and Upgradable Connectivity
The IN200 Evolution offers generous connectivity with 5 RCA analog inputs and a Bypass input for use as a power block. Two pre-out outputs allow for bi-amplification or the addition of a subwoofer. A 6.35 mm headphone jack is present on the front. The device remains compatible with optional DAC cards DA100 and DA200, offering up to 2 coaxial inputs, 2 optical inputs, 1 USB-B input (PCM up to 32 bits/384 kHz and DSD128), and a Bluetooth receiver.
Power and Control for Easy Speaker Management
With a power output of 2 x 120 W at 8 Ω and 2 x 200 W at 4 ohms, including 2 x 50 W in pure class A, the IN200 Evolution has substantial current reserves. It can easily drive a wide range of speakers, even the most demanding ones. Its extended bandwidth from 5 Hz to 100 kHz and fast rise time of 2.5 µs ensure great responsiveness and excellent definition across the entire audio spectrum.
Advanced Features for a Customized Experience
The IN200 Evolution incorporates new practical features accessible via its menu. You can adjust and save the balance, rename inputs, and finely manage power settings such as preheating time or automatic standby. The provided remote control allows complete control of the device as well as other Atoll components (CD players, tuners, DAC).
A Lively and Natural Musical Reproduction
When listening, the Atoll IN200 Evolution impresses with its ability to reproduce music with accuracy and naturalness. The bass is deep and perfectly controlled, providing a solid foundation for the sound structure. The midrange stands out for its great neutrality and striking realism, with voices having a haunting presence. The treble, precise and detailed, brings a beautiful brightness without ever becoming aggressive. The soundstage, wide and deep, completely frees itself from the speakers.
What are the main improvements made to the IN200 Evolution compared to its predecessor?
The IN200 Evolution benefits from several notable advancements, including a more powerful 10 VA digital transformer, new tellurium copper speaker outputs derived from the IN300, high-precision current sources for better stability, and new features accessible via the menu such as balance management and power settings.
Is the IN200 Evolution compatible with optional DAC cards?
