Overview
Mimesis 18.4
The Goldmund Mimesis 18.4M. is the mono amplifier of the Goldmund "High-End" line of products. The size of half a Mimesis 28M and using a recently improved version of the JOB 4 circuit, it provides unique convenience with a built-in digital input, auto-start circuit with signal-sensing and input attenuator Its new version of the JOB 4 circuit makes it also the most advanced amplifier in the Goldmund line and provides it with an exceptional sound quality in addition to its unique functionality.
