ECI 6 MKII Integrated Amplifier

Pure analogue architecture and high-current control unburdened by digital circuitry.

The ECI 6 MKII is engineered exclusively for the high-fidelity purist who prefers to keep sensitive digital processing completely separate from the core amplification path. By dedicating the entire chassis solely to the handling of analogue signals, Electrocompaniet has eliminated any potential for high-frequency digital noise to encroach upon the music. This uncompromising approach ensures that the amplifier preserves the absolute integrity of the incoming signal with an exceptionally low noise floor. Positioned as the core analogue foundation within the brand's legendary Classic Line, this model builds upon the celebrated lineage of the ECI 5 MKII while introducing vital engineering refinements. It features an extensively upgraded power supply alongside a highly sophisticated preamplifier module. For listeners whose digital needs inevitably evolve, the factory design allows for a seamless, modular path to full streaming capability later on, preserving long-term flexibility without sacrificing current performance. Sonically, the ECI 6 MKII delivers a deeply communicative, fluid presentation that avoids the dry, skeletal character common to lesser solid-state designs. It is renowned for its authoritative low-frequency control, an expansive holographic midband, and a completely natural, fatigue-free high-frequency extension. Backed by a peak current capability exceeding 100 Amperes, it maintains a vice-like grip and calm composure over complex musical passages, regardless of how demanding or erratic the loudspeaker impedance becomes.

Key Features

01

Zero-Feedback Class-A Preamplifier

The input stage is meticulously constructed from discrete circuits running entirely in pure Class-A with zero negative feedback to preserve absolute harmonic accuracy.

02

High-Current Power Supply Upgrade

Equipped with a beefed-up linear transformer and massive energy reserves, allowing the output stage to deliver a peak current exceeding 100 Amperes with absolute stability.

03

Balanced Output Topology

Utilises a fully balanced configuration from input to output, netting an exceptional noise floor of minus 135dB for deep black backgrounds and superb micro-dynamic contrast.

04

Modular Upgrade Path

Intentionally designed to be completely future-proof, the internal architecture can be converted at any time to the streaming DX specification via an official factory module.

Preamplification and Current Delivery

Chapter 01

Preamplification and Current Delivery

At the heart of the ECI 6 MKII lies a design philosophy that balances open loop linearity with rigid speaker management. While the discrete Class-A preamplifier stage avoids feedback entirely to remain exceptionally open and unstrained, the output stage employs a carefully tailored, moderate amount of negative feedback. This precise calibration delivers deep, articulate bass extension and absolute cone control while maintaining the warm, detailed top-end texture that defines the historic Electrocompaniet sound.
Purist Analogue Connectivity

Chapter 02

Purist Analogue Connectivity

The rear panel is configured strictly for high-end analogue deployment, hosting a true balanced XLR input alongside three single-ended RCA stereo inputs. To support bi-amplification, active subwoofers, or external recording equipment, the unit includes both balanced XLR and single-ended RCA preamplifier outputs. It also features a dedicated Home Theatre direct input, allowing the ECI 6 MKII to take over front-channel driving duties seamlessly within a broader multi-channel environment.
Chassis Rigidity & Industrial Design

Chapter 03

Chassis Rigidity & Industrial Design

The MKII iteration introduces an overhauled mechanical framework designed to isolate sensitive audio signals from acoustic feedback. The upgraded chassis is notably stiffer and heavy, finished with the brand's unmistakable 10mm thick acrylic faceplate. Four gold-plated buttons govern navigation, while the glowing volume indicator traces a mechanically driven, smooth arc around the central insignia, providing a tactile and visually authoritative presence in the listening room.
