ATOLL Electronique Unveils New Evolution 400 Series Flagship Audio Components

Experience refined audio excellence with the new ATOLL Evolution 400 Series, engineered for audiophiles seeking top-tier performance and sophisticated design.

Elevating High-End Audio: The New Evolution 400 Series

When it comes to high-end audio gear, nothing beats the thrill of unboxing a meticulously crafted component that promises to redefine your listening experience. ATOLL Electronique, a French manufacturer renowned for its high-quality audio electronics, has just taken a significant leap forward by launching its all-new Evolution 400 Series — a fresh take on their celebrated 400 Signature lineup.

The Evolution 400 (400 Series EVO) introduces five flagship models that combine cutting-edge technology, premium build quality, and ATOLL’s signature commitment to exceptional price-to-performance balance. These new components are not only engineered for superb sound but also crafted with an eye for style and durability, all hand-made in France with top-tier parts and featuring a discrete symmetrical architecture.

The Evolution 400 Series Lineup: A Symphony of Precision

The new flagship Evolution 400 range consists of five models, each tailored to elevate your audio system:

• IN400 EVO Integrated Amplifier
• PR400 EVO Preamplifier
• AM400 EVO Power Amplifier
• CD400 EVO Top-loading CD Player
• DR400 EVO Top-loading CD Transport

Each model is designed to work harmoniously within a hi-fi setup, delivering clarity, power, and precision that audiophiles dream about.

Design and Build: Robust Elegance with a Modern Twist

ATOLL has reimagined the mechanical design of the 400 Series EVO line with sturdy 2 mm steel chassis complemented by 10 mm thick, brushed, micro-blasted, and anodized aluminum front panels. These faceplates bear finely engraved details that add a touch of sophistication.

Mechanical stability is paramount: side heatsinks made from solid aluminum blocks not only ensure efficient heat dissipation but also absorb mechanical vibrations, ensuring the sound remains pristine and undistorted. Moving away from the previous sculpted aesthetics, the new lineup sports a squared-off design that integrates effortlessly with other audio equipment while maintaining a sleek, elegant presence.

Available in classic black or natural aluminum silver finishes, these components look as stunning as they sound.

PR400 EVO Preamplifier: Dual-Mono Brilliance

The PR400 EVO ($6,600) stands as ATOLL's latest flagship preamplifier, boasting a true dual-mono architecture that uses one low-noise linear transformer per channel. This design ensures outstanding channel separation and purity.

Critical components like the selection relays are separated for each channel, while premium MKP coupling capacitors are housed in independent enclosures, shielding them from interference. The volume control is elegantly handled by two synchronized ALPS motorized potentiometers, ensuring smooth and precise adjustments.

This preamp is a testament to ATOLL’s dedication to sonic purity and engineering excellence.

AM400 EVO Power Amplifier: Power Meets Precision

Delivering 170 watts per channel into 8 ohms and a robust 320 watts into 4 ohms, the AM400 EVO ($6,600) is a powerhouse designed for audiophiles who demand muscle without compromise. In bridged mono mode, it pumps out a staggering 600 watts.

Featuring four pairs of MOSFET transistors per channel, the amplifier is insensitive to capacitive loads — a crucial trait for maintaining sound fidelity with complex speaker systems. High-quality MKP crossover capacitors and custom low-resistance filter capacitors crafted by a renowned specialist preserve the purity of the signal.

ATOLL’s attention to detail extends to the wiring: speaker output cables are pure, oxygen-free silver-plated copper with Teflon insulation, and tellurium copper speaker plugs ensure seamless transmission of every sonic nuance.

IN400 EVO Integrated Amplifier: All-in-One Excellence

Audiophiles who prefer an integrated solution will find their match in the IN400 EVO ($7,000). This unit merges the power and finesse of the 400 EVO separates into a sleek single chassis.

It delivers a potent 180 watts per channel into 8 ohms and 300 watts into 4 ohms, featuring a true dual-mono design for impeccable channel separation. Connectivity options abound, including two XLR line level inputs, five RCA inputs, a home-theater bypass, dual pre-outs, and a 12V trigger output — perfect for flexible setups.

DR400 EVO CD Transport: Precision Mechanical Engineering

Replacing its predecessor, the DR400 EVO ($5,600) sets a new standard as a top-loading CD transport. It features ATOLL's latest mechanical innovation, including a solid aluminum platter and an optimized anti-vibration system.

The unit employs a high-speed differential line drive for formatting S/PDIF and AES/EBU digital signals, ensuring crystal-clear data transmission. Its digital stages and power supplies are carefully designed to maximize audio realism and density, making it an essential foundation for any serious CD system.

CD400 EVO CD Player: A Dual-Mono Digital Marvel

At $7,900, the CD400 EVO is a top-tier CD player that also doubles as a high-end digital-to-analog converter. Building on ATOLL’s top-loading mechanics, it features bi-polar Class A audio stages without feedback, driven by dual Burr Brown PCM 1792 DACs — one dedicated to each channel.

Its true dual-mono architecture ensures an immersive stereo image and sonic realism. Inputs include coaxial, optical, and USB digital ports, allowing the player to function as a converter for various digital sources.

Outputs are versatile too, with both XLR analog and AES/EBU digital connectors.
