PrimaLuna ProLogue Two

The Prologue 2 is an integrated amplifier using KT-88 output tubes with an output power of 2 x 40 W.

It is equipped with the exclusive PrimaLuna Adaptive AutoBias circuit that continuously adjusts the bias of the output tubes, making it unnecessary to match them and extending their life while reducing distortion by up to 40%.

The exclusive PrimaLuna low-loss wideband output transformers offer optimized phase characteristics. The very low feedback (6 dB), low noise level and very wide bandwidth allow optimal reproduction of micro-information.

Excellent impulse response and high output power allow the Prologue 2 to easily drive any type of speaker. Vinyl enthusiasts will be delighted to know that the Prologue 2 is ready to receive the optional ProLogue MM-Phono phono card.
