ECI 6 MKII Integrated Amplifier

The new 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, we have equipped the ECI 6 MKII with an even better power supply and a more sophisticated preamplifier module.

As a result we can offer you an extremely substantial and dynamic amplifier, capable of controlling a wide range of speakers on the market.

Sit down today in an Authorized Electrocompaniet Dealer’s store and listen — one more thing those online sites can’t offer — an in-store demo! Please check with your local distributor or us if you are uncertain, or contact us.



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


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.

Modular construcrion

The ECI 6 MKII is upgradable to ECI 6 DX MKII. Please contact your dealer for pricing and availability.
