ECI 6 DX MKII Integrated Amplifier / DAC / Streamer

Uncompromising high-current amplification paired with state-of-the-art lossless streaming.

The ECI 6 DX MKII represents the definitive modern iteration of Electrocompaniet's high-power integrated architecture, designed to reconcile the convenience of modern network audio with the strict principles of traditional analogue engineering. Rather than treating digital connectivity as an afterthought, this flagship model fully assimilates an advanced software streaming engine directly alongside an extraordinarily robust, high-current power supply. The result is a single-chassis masterpiece that eliminates the necessity, complexity, and cable clutter of separate digital front-ends. Positioned at the pinnacle of the brand's integrated component family, the unit is constructed on an extensively upgraded, resonance-damping framework that structurally isolates sensitive circuitry from external mechanical vibrations. Inside, it utilizes a sophisticated preamplifier module derived from the brand's separate reference components, which feeds a highly linear output stage capable of delivering massive current reserves. It acts as an authoritative operational hub, effortlessly managing both traditional analogue sources and high-resolution network streams with identical mechanical precision. Sonically, the amplifier yields an immense, natural soundstage marked by the rich tonal substance and organic flow that recording studios have prized in the brand for fifty years. It steers entirely clear of the dry, skeletal presentation typical of modern high-power solid-state designs, offering instead a deeply fluid midrange, superb micro-dynamic texture, and a vice-like grip over the lowest musical octaves. Even when partnering with notoriously difficult, low-impedance loudspeakers, its transient delivery remains calm, collected, and unfailingly musical over hours of uninterrupted listening.

Key Features

01

High-Current Dual-Mono Design

Features a massive linear power supply and an output stage capable of generating peak currents exceeding 100 Amperes, maintaining complete control over erratic speaker loads down to 2 Ohms.

02

Proprietary EC Streaming Engine

Built around a powerful, future-proof network board that natively handles Tidal Connect, Qobuz Connect, Spotify Connect, Roon Ready streaming, and lossless DSD128 decoding via a dedicated mobile app.

03

Asynchronous Reference DAC

Utilises a precision 24-bit/192kHz digital-to-analogue converter and sample rate converter with an asynchronous USB input, meticulously isolating digital jitter from the pure analogue pathways.

04

Balanced Analogue Architecture

True balanced circuit topology throughout the preamplifier stage ensures an exceptionally low noise floor of minus 135dB, preserving absolute signal purity and micro-detail resolution.

The Evolution of the MKII Chassis

Chapter 01

The Evolution of the MKII Chassis

The ECI 6 DX MKII benefits from an extensively revised physical architecture that goes far beyond simple cosmetic enhancement. The housing features an upgraded, noticeably stiffer construction to effectively eliminate microphonic distortions caused by room resonance. On the front, the signature 10mm thick acrylic fascia is modernised with discrete gold-plated controls and a floating volume marker that moves in a smooth arc around the central power symbol, maintaining a timeless Scandinavian presence on the equipment rack.

Comprehensive Connected Luxury

By treating network audio with the same seriousness as physical inputs, this amplifier hosts an ocean of digital and analogue connectivity. The rear panel provides a fully balanced XLR input alongside three single-ended RCA inputs, supplemented by five digital connections including asynchronous USB and dual optical ports. Network stability is anchored by a high-speed Gigabit Ethernet connection and advanced 802.11 AC Wi-Fi with MIMO technology, ensuring uninterrupted transmission of ultra-high-resolution files.

Listening Notes

When auditioned across demanding symphonic and acoustic pieces, the ECI 6 DX MKII showcases an authoritative, velvety, and emotionally communicative presentation. It renders complex multi-instrumental passages with a holographic depth that completely fills the room, trading forward analytical brightness for a natural, silky treble decay and a dense, foundational lower-octave authority that makes recordings feel tangibly alive.
