AW250R Stereo Amplifier

Uncompromising high-current stereo power capable of mastering severe loudspeaker loads.

The AW250R stands as an enduring monument to Electrocompaniet's masterful implementation of high-current power delivery. Weighing in at a substantial 39 kilograms, this pure high-fidelity workhorse is engineered to bypass the physical and operational limitations that cause conventional solid-state amplifiers to buckle under demanding dynamic swings. By prioritizing massive energy storage alongside a direct-coupled topology, it ensures that your system maintains a steadfast structural stability during full-scale orchestral peaks. Positioned as the core high-power stereo anchor within the brand's celebrated Classic Line, the AW250R introduces a level of engineering refinement that bridges the gap between traditional separates and modern multi-chassis arrays. The electronic architecture features a dual-mono configuration that shares only the mains entry point, effectively isolating signal currents across both channels to ensure a vanishingly low noise floor and deep inter-channel independence. For exceptionally vast listening environments, an integrated balanced link allows the unit to seamlessly connect to additional stages for bi-amplification or bridged mono operation. Sonically, the AW250R delivers an incredibly fluid, translucent and non-fatiguing presentation that models the organic, three-dimensional warmth of fine valve equipment without sacrificing the absolute grip of solid-state execution. The music materializes from a dark, velvet background space, presenting an expansive soundstage that resolves complex mid-band textures and acoustic room cues with natural clarity. Low-frequency management is characterized by an unyielding, tactile authority and deep bass damping, guiding the lowest musical octaves with total, stress-free composure.

Key Features

01

Floating Transformer Technology (FTT)

Utilises a specialized power supply architecture capable of delivering twice the current of conventional power designs, vastly lowering overall distortion and noise while stabilizing power rails.

02

Exceptional Peak Current Reserve

Engineered to deliver a massive peak current exceeding 100 Amperes, allowing the output stage to comfortably manage volatile speaker impedances scaling all the way down to 1 Ohm.

03

Balanced XLR Link Connectivity

Features dedicated rear-panel balanced XLR link outputs for each channel, simplifying the integration of secondary power amplifiers for advanced multi-amplifier or bi-amping configurations.

04

Double Set Binding Posts

Outfitted with high-grade, heavy-duty double sets of speaker terminals for both the left and right channels, configured specifically to accommodate audiophile bi-wiring setups.

The Evolution of a Modern Classic

Chapter 01

The Evolution of a Modern Classic

While the external silhouette of the AW250R remains faithful to Electrocompaniet's historic industrial design, the internal layout has undergone a series of significant modern engineering upgrades. Every single output transistor has been modernized to a higher-specification component for absolute thermal stability and tighter bass management. Simultaneously, the gain stages have been accelerated with lower-noise, faster-rectifying power components to unlock a dramatic shift in resolution, transparency, and micro-acoustic precision.
Pure Balanced Architecture

Chapter 02

Pure Balanced Architecture

Adhering to strict balanced link principles, the rear panel is built intentionally around low-noise XLR inputs to maintain total signal integrity between the preamplifier and power stages. The internal discrete audio paths operate with an ultra-low output impedance of less than 0.008 Ohms across the entire audible frequency range. This guarantees that the amplifier's internal circuits remain fully shielded from incoming radio-frequency interference and mechanical noise floors.
Listening Notes

Listening Notes

When auditioned alongside challenging, low-sensitivity loudspeakers, the AW250R reveals an authoritative, dark-wrapper tonal quality that adds life and physical substance to instruments without inducing forward analytical listener fatigue. Vocals are handled with an uncanny, rounded realism, while massive dynamic swings in percussion and brass are negotiated with a relaxed headroom that leaves the acoustic architecture of the original room entirely unperturbed.
