Product Features
Engineering Derived from the CEN.GRAND Flagship System
The Maxwell 909 inherits its design philosophy from the acclaimed CEN.GRAND 9i‑938/958 pre‑amplifier and power amplifier system. While more compact, it preserves the core sonic attributes of the reference models: neutrality, smoothness, refined analog character, and a deep sense of musical coherence. This lineage ensures that the Maxwell 909 performs not merely as an integrated amplifier, but as a unified reference platform.
Absolute Balanced Linear Equalization (ABLE) Architecture
At the heart of the Maxwell 909 is the ABLE pre‑amplification stage, a fully balanced input‑to‑output topology engineered to maintain symmetrical signal flow. This architecture minimises distortion, suppresses noise, and preserves micro‑detail, allowing the amplifier to reproduce music with exceptional clarity and tonal accuracy. The result is a presentation that is both highly resolving and effortlessly natural.
Immense Power with Absolute Control
A purpose‑built 2,000‑watt high‑capacity power supply forms the foundation of the Maxwell 909’s performance. This supply feeds a dual‑input, fully balanced power amplification stage capable of delivering:
500 W per channel into 8 ohms
1,000 W per channel into 4 ohms
Such power is not simply about volume—it is about control. The Maxwell 909 maintains composure under dynamic swings, grips loudspeakers with authority, and reveals the full tonal and spatial information embedded in the recording. Large, multi‑driver loudspeakers are driven with ease, allowing the amplifier’s sonic qualities to be fully realised.
Two Distinct Sound Modes
The Maxwell 909 offers two selectable operational modes:
Integrated Mode engages the full ABLE pre‑amplification stage, delivering maximum resolution, dynamic contrast, and tonal precision.
Pre-Bypass Mode bypasses the pre‑amp for a shorter signal path and a slightly softer, more relaxed sonic character.
A clear on‑screen indicator confirms the active mode, ensuring intuitive operation.
Precision Volume System with Intelligent Protection
The volume control operates from –65 dB to +4 dB and incorporates an intelligent protection mechanism. In the unlikely event of a fault—such as an uncontrolled rise in output—the system automatically reduces the volume to –50 dB and alerts the user via a flashing indicator. Normal operation resumes once the physical volume knob is returned to a safe position.
Thoughtful User Experience
The Maxwell 909 is designed for seamless daily use:
Balanced (XLR) and single‑ended (RCA) inputs accommodate a wide range of high‑end sources.
The included remote control provides access to essential functions, including input selection and sound‑mode switching.
Power on/off remains a deliberate, tactile action via the front panel or rear main switch.
The display provides clear feedback on volume, input, and mode.
Despite its immense capability, the amplifier remains elegant and understated—built to integrate naturally into refined listening environments.
Sonic Character
The Maxwell 909 is defined by three core sonic qualities:
Neutrality — faithful reproduction without coloration.
Smoothness — a refined, analog‑like flow that encourages long listening sessions.
Musicality — a coherent, emotionally engaging presentation that reveals the intent of the performance.
Whether paired with highly resolving monitors or large full‑range loudspeakers, the Maxwell 909 delivers a balanced, authoritative, and deeply musical experience.
