Mimesis Reference

The Mimesis Reference is Goldmund’s reference analog preamplifier, with the preamplifier and its power supply in separate enclosures. Class A output stage drivers and carefully selected ultra-low-noise components keep harmonic, intermodulation and transient intermodulation distortion to a minimum.

The power supply was completely redesigned, with separate analog and digital circuits, custom audio-grade transformers and a dedicated supply for each channel, for better channel separation. A heat sink machined in-house cools the supplies, and every low-noise op-amp on the audio board has its own heat sink, machined from a single piece of aluminum.

The 2023 design has a screwless top panel and 12 mm panels throughout, in Goldmund’s silver grey or matte black, with a gold or matching top ring.
