MIMESIS 37S NEXTGEN
Preamplifier

Goldmund Mimesis 37S NextGen is a high-end analog stereo preamplifier. Its ability to reduce noise and distortion using multiple parallel preamplifier stages is purely incredible. A Full Dual-Mono construction with processor-driven linked attenuators, the Mimesis 37S NextGen uses a separate power supply unit for optimum noise reduction and 2 successive stages of power regulation with 4 separate circuits.
