MIMESIS 27.8

SWISS PRECISION

The swiss precision of Mimesis 27.8 construction and the quality of the materials that we use reinforce the solid yet refined look which characterizes our products since the company’s inception. The precise assembly and rigid mechanics of the Mimesis 27.8 make its response incredibly accurate at both high and low levels.

LIVELY & TRANSPARENT

Equipped with digital and analog inputs, the Mimesis 27.8 integrates the Alize 6 DAC circuitry. As traditionally with Goldmund preamplifiers, the Mimesis 27.8 preamplifier is fully transparent and offers an outstanding signal / noise ratio. In the realm of entertainment, the ultimate component of your passive audio system. Ready to meet the needs of the most demanding users.
