About the ProLogue 3

The PrimaLuna ProLogue 3 is a tube line-stage preamplifier designed with a true dual-mono architecture, employing two toroidal power transformers and choke-regulated power supply for excellent channel separation and low noise. It uses tube rectification with two 5AR4 tubes, and includes two 12AX7 and two 12AU7 tubes in its complement. The design avoids negative feedback and cathode followers to preserve a vibrant midrange and three-dimensional soundstage. It features point-to-point wiring, premium parts such as Alps Blue Velvet potentiometer and Solen capacitors, and a hand-rubbed finish. The preamplifier offers four pairs of RCA inputs and two pairs of RCA outputs plus one tape output, allowing easy bi-amping or subwoofer integration. It is well-suited for pairing with tube or solid-state amplifiers, providing wide bandwidth, real bass, and extended top-end without harshness. The ProLogue 3 is noted for its low gain (approximately 12dB), low noise, and excellent signal-to-noise ratio, making it ideal for high-efficiency speaker systems and audiophile setups.
