PrimaLuna DiaLogue Four silver

Responding to the demands of the most discerning audiophiles, the new series of DiaLogue stereo or mono separate amplifiers crosses a new threshold and redefines the notion of high-performance, high-end audio within reach of all enthusiasts.

The new DiaLogue 4 stereo amplifier represents an entirely new PrimaLuna design with no global feedback and innovative phase-shifting and driver circuits. The DiaLogue 4 is also equipped with the award-winning, often copied but never equaled PrimaLuna Adaptive Auto Bias and SoftStart circuits.

Low-noise, high-current driver circuits ensure extended bandwidth at high power, very low phase distortion, and superlative impulse response. The rectifier circuits are ultra-fast, low-noise designs.

The wide-bandwidth, low-loss PrimaLuna output transformers are matched and have optimized phase characteristics. Very high quality capacitors are used in the signal path as well as in the power supply to provide higher acoustic resolution and increased dynamics on micro-signals.
