Norse X2 Preamplifier

X2 Pre-Amplifier

High-End Discrete MOSFET Preamplifier

This preamplifier employs a pure single-ended MOSFET gain stage, carefully optimized for exceptional linearity, ultra-low noise, and a natural, effortless sound signature. The design maintains a fully discrete signal path that is DC-coupled throughout, featuring a current-loaded output stage for maximum linearit preserving signal integrity while delivering the characteristic warmth and musicality typical of well-executed single-ended MOSFET designs. Volume control is implemented through a high-precision relay attenuator using premium 0.01% tolerance metal-film resistors in a ladder or switched-resistor topology. This approach guarantees outstanding accuracy, perfect channel matching, and absolute transparency, with no degradation in sound quality even at the lowest listening levels.

Connectivity:

• 4 pairs of balanced XLR inputs

• 3 pairs of balanced XLR outputs (perfect for bi-amping or simultaneously driving multiple power amplifiers and subwoofers)

Additional Refinements:

• Ultra-low noise power supply with multiple stages of regulation and extensive decoupling

• Microprocessor-controlled relay switching for silent input selection and muting

• High-quality input and output relays with gold-plated contacts

• Minimalist signal path with the shortest possible routing and premium-grade components

• Remote control

This DC-coupled, current-loaded single-ended MOSFET architecture delivers reference-level performance: outstanding dynamic range, superb channel separation, effortless micro-dynamics, and precise control. It combines the engaging musicality and harmonic richness of single-ended MOSFET operation with the accuracy, speed, and drive capability demanded by modern high-end audio systems.

Why Choose the Norse System?

The Norse Audio System combines flexibility, performance, and value. Start with a single X1 Power Amplifier in stereo mode and scale up to a dual-mono configuration using the same X5 Power Supply. This modular design grows with your needs, whether upgrading speakers or experimenting with new setups.

Adjustable bias settings let you tailor the sound signature, while the X5’s robust power delivery ensures dynamic, clear audio. The result is a high-performance system that delivers exceptional clarity, dynamics, and musicality at an accessible price.
