Product Highlights

The PrimaLuna ProLogue Four is a vacuum-tube stereo power amplifier delivering 35 Watts per channel into 8 ohms and 4 ohms. Utilizing a pair of EL34 tubes per channel, it produces a warm "British" sound profile characterized by smooth tonality and notable musicality. This hand-made amplifier features point-to-point wiring and the signature Adaptive AutoBias™ circuit, which continuously adjusts tube bias to eliminate manual calibration while significantly reducing distortion. Built with premium components including a custom toroidal power transformer, Nichicon capacitors, and Soft-Start circuitry, it ensures high-bandwidth performance and extended component life for a consistently reliable listening experience.

Consistently recognized with Stereophile Recommended Component status and The Absolute Sound Editor’s Choice Awards, the ProLogue Four is lauded by critics for its unbeatable value and ability to compete with significantly more expensive designs. Reviewers highlight its sophisticated engineering and refined presentation as a hallmark of the PrimaLuna brand. This power amplifier offers an exceptional blend of reliability and high-fidelity tube performance, serving as a definitive foundation for any serious audio system.
