About the Jazz

The Nagra Jazz preamplifier is a valve-based high-fidelity preamplifier designed as a successor to the Nagra PL-P and PL-L models. It features a completely rethought electronic design for improved stability, reduced noise, and exceptional transparency. The unit uses 2x 12AX7/ECC83 and 1x 12AT7/ECC81 vacuum tubes selected by Nagra's laboratory for optimal performance. It includes a precise Nagra-made modulometer for volume and balance control, allowing fine tuning and level matching. The preamplifier has five line inputs (four RCA single-ended and one XLR input, which can be optionally balanced with transformers). It is powered by an external Nagra ACPS II power supply module. The chassis is compact and vibration-isolated, with gold-plated military-grade circuit boards and carefully chosen components for durability and sound quality. The Jazz offers a deep, natural, highly defined sound image with a wide bandwidth and low distortion, making it suitable for audiophiles seeking high-end performance.
