Nagra Melody preamplifier transistor mosfet front modulometer VFS

Manufactured from 2012 to 2018


High-end solid-state preamplifier

The Nagra MELODY solid-state preamplifier establishes new levels in terms of sonic transparency and exactitude. Everything within its high precision electronics contributes towards musical realism respecting the slightest detail and nuance. The Nagra MELODY maintains the traditional ergonomics and Nagra look, with the modulometer on the front face to indicate the output signal level.

Circuit design

The Nagra MELODY is built using exclusively discreet components of audiophile quality, and transistors that are individually tested and matched. Levels can be increased by 12 dB using a simple switch, thus the preamplifier can comfortably handle sources supplying weak output signal levels. The design concept allows the Nagra MELODY to operate in a sovereign silence and perfect stability, leaving the music to display its detail in total harmony.

Remote control

Remote-controllable (Volume and Mute)

The Nagra MELODY sports five inputs on RCA connectors and two switchable outputs, one on RCA and the other on XLR connectors. The latter can be bridged with the XLR input if needed for Home cinema application.

Phono option

The Nagra MELODY can be equipped with a high-performance phono stage, inspired from the renowned Nagra BPS preamplifier. This phono module accepts both MM and MC signals, it features Nagra hand-wound step-up transformers identical to those in the BPS and VPS.

Power supply

You may choose to use the built-in power supply to run the Melody. If you wish to take the Melody to the next level, you can upgrade it with an external power supply, either the ACPS-II or even better, the fully-fledged MPS multiple power supply.
