The ECI 6 MKII is a powerful integrated amplifier equipped with 4 analogue inputs. The ECI 6 MKII offers 2 x 125 Watts and is based on the successful ECI 5 MK II. To enhance it, Electrocompaniet have equipped the ECI 6 MKII with an even better power supply and a more sophisticated preamplifier module.
As a result, Electrocompaniet can offer you an extremely substantial and dynamic amplifier, capable of controlling a wide range of speakers on the market.
Improved
Connectivity
Analogue sources can be connected to one balanced (XLR) input and three single-ended (RCA) stereo inputs. With two preamplifier outputs, one balanced and one single ended, the ECI6-MKII is ready for future expansions.
Improved
Balanced Sound
The input stage is built from discrete circuits running in class A with zero feedback. The output stage runs with moderate amounts of negative feedback, carefully balanced between good bass extension and control, a detailed open midrange and a warm detailed top.
Proprietary Volume Control
The ECI 6 MKII uses Electrocompaniet’s proprietary, fully electronic volume control — a decade in development — that eliminates mechanical switches, relays or stepped attenuator contact paths in the audio signal. It offers extremely fine resolution (about 0.1 dB steps across 1000 steps) while keeping the signal path length and topology constant regardless of volume setting.
Key Architectural Features
The ECI 6 MKII is a fully discrete, balanced, dual-mono preamplifier operating in pure Class A with independent power supplies per channel and heavy storage capacitance. That hardware platform (plus the “AmpliWire”/high open‑loop‑bandwidth topology and low negative feedback) reduces distortion, keeps phase coherence, and preserves channel separation.
Dual‑mono layout and strong channel isolation reduce crosstalk, so left/right separation stays vivid even at low playback levels—critical for depth and lateral imaging.
Unlike volume implementations that change attenuation topology, insert switching, or introduce varying impedance/phase shifts at different settings, the ECI 6 MKII’s approach aims to keep the electronics “disappear” and the recording’s spatial information intact from whisper-quiet to room‑filling levels. The result—when combined with good amplification and speakers—is more consistent staging, stable instrument placement, and preserved holographic depth across volume.
Constant signal path and no switching means the electrical length, impedance and phase behavior don’t change as you move the volume—so imaging cues (timing and phase) remain stable at any level. Very fine, repeatable steps (0.1 dB) let you set absolute level without upsetting channel balance or relative microdynamics, which helps keep the soundstage center, depth and instrument positions intact.
