CD PLAYER · CD400 EVO
Front view of the CD400 EVO CD player in brushed aluminum finish.
Presentation
The CD400 Evolution is equipped with the latest top-loading mechanics developed by ATOLL. The audio stages and power supplies have been reworked to provide even greater realism and greater ease in rhythmic tracking. The chassis features solid aluminum sides machined from a single block to ensure perfect mechanical inertia. They optimally absorb all vibrations. The playback unit specifically developed for the 400 series is made of vibration-resistant aluminum mechanical elements decoupled from the device's chassis. This system significantly improves playback quality and consequently reduces the intervention of error correction circuits. This translates into extremely fine tones and a sumptuous treble response. The digital signals are perfectly shielded and follow an optimized path to combat jitter. The use of two independent converters, one per channel, prevents crosstalk and significantly improves the signal-to-noise ratio and dynamics. Finally, the CD400 Evolution has high-quality digital inputs built-in, leveraging the internal converters. From this perspective, it should also be considered a high-end DAC.

Presentation
The IN400's design is based on technical and aesthetic choices dedicated to optimal musicality. Mechanically, the chassis is made of 2 mm steel, the front panel of 10 mm aluminum. The side heatsinks are machined from solid aluminum blocks to absorb mechanical vibrations and ensure perfect heat dissipation. The power stages are rigorously dual mono with a specific attenuator per channel and two differentiated star-shaped grounds. Each component was selected through listening, and the circuit layout optimized to fine-tune each bias current and feedback ratio. The IN400 EVO features eight rigorously matched MOS-FET transistors per channel. The ultimate goal is to deliver maximum power and energy across all registers. The result is a sound experience that combines sonic substance and fluidity, naturalness and harmonic richness.

PREAMP · PR400 EVO
Front view of the PR400 EVO preamplifier in brushed aluminum finish.
Presentation
The PR400 Evolution operates entirely in dual mono with a low-noise transformer per channel. The potentiometers and selection relays are also separate for the two channels. The coupling capacitors (high-end MKP) are shielded in independent enclosures to avoid any radiation problems. The volume is controlled by two independent and perfectly synchronized ALPS motorized potentiometers. We use a proprietary servo system based on non-intrusive real-time audio measurement. The display used is a low-power OLED model chosen for its excellent contrast and low electromagnetic radiation. Furthermore, its power supply, as well as that of all control devices, is completely independent of the audio power supplies. The discrete audio stages have a purely symmetrical structure; the circuit is based on a dual-input differential pair and an original Class A biased circuit with very low feedback. This structure minimizes both overall distortion and intermodulation distortion. This promotes the spatial and material perception of the instruments, listening gains in realism and expressiveness.

AMP · AM400 EVO
Front view of the AM400 EVO amplifier in brushed aluminum finish.
Presentation
The power stages feature eight MOS-FET transistors per channel, providing considerable power, perfectly controlled thanks to carefully designed audio stages. The circuit has been optimized to make the device insensitive to capacitive loads. The filter capacitors, with low series resistance, are custom-designed by a leading specialist. The MKP technology link capacitors were selected through careful listening; they are shielded in separate enclosures to prevent any electromagnetic interference. The connecting cables between the motherboard and the speaker outputs are made of pure, oxygen-free, silver-plated copper with Teflon insulation. These cables are custom-made by one of the best French audio cable manufacturers. The proprietary tellurium copper speaker output plugs were developed for their ability to transmit all the energy and micro-details of the electrical signal without alteration. The polypropylene film structure link capacitors were selected through careful listening from the high-end series of leading manufacturers. In bridged mono mode, the power output increases to 600 W/8 Ω: this operation is suitable for all systems requiring high power. The differential structure design allows this transformation to be achieved without altering the nuances of the musicality; the gain in "sound material" makes the listening experience even more realistic.
