Audio Note (UK) M2 Line Preamplifier

The Audio Note (UK) M2 Line Preamplifier is designed to prioritize sonic performance over technical specifications. It meets the criteria of Audio Note (UK) Level 2, which includes pure Class A operation, zero negative feedback, single-ended circuit topology, valve rectification, and high-quality materials and components.

The M2 Line Preamplifier uses a single-ended, zero feedback circuit topology, which is known for its simplicity and linearity. This design eliminates the need for a phase splitter, which can introduce crossover distortion in other amplifier designs.

This preamplifier uses a 6SN7 tube in its line stage, which is known for its high linearity and low noise. The 6SN7 is a dual triode tube, which means that each tube contains two independent triode sections that can be used for different stages of amplification.

In addition, the M2 Line uses a valve rectified power supply, which includes a 6X5 and an ECL82 tube. The 6X5 is a full-wave rectifier tube, which converts the AC voltage from the mains power into a DC voltage that can be used to power the amplifier circuitry. The ECL82 is a triode-pentode tube, which is used in the voltage regulation stage of the power supply.

Using valve rectification can provide a more natural and musical sound compared to solid-state rectification. This is because vacuum tube rectifiers have a softer, more gradual voltage ramp-up than solid-state rectifiers, which can result in less stress on the power supply capacitors and a more natural sound.

Overall, the use of high-quality tubes and a valve rectified power supply in the M2 Line Preamplifier is designed to provide a high level of musicality and sound quality. It is a product of careful engineering and attention to detail, and is well-suited for use in high-end audio systems.
