Aune N7 - Headphone Amplifier Class A

Aune N7 is a fully discrete Class A headphone amplifier and preamplifier that combines the warm, analog character of classic amplifiers with modern precision. With its advanced twin-JFET input, R2R volume control, and two-stage Class A power control, the N7 delivers a detailed, musical soundstage with outstanding fidelity to the original – all packed in an elegant aluminum chassis.

• Pure Class A Performance: The N7 consistently operates in true Class A mode with a specially developed two-stage power control, providing a silky smooth and harmonic sound with natural warmth and fullness. Perfect for audiophiles seeking a tube-like sound character.

• Twin-JFET Input: By using a precisely matched twin-JFET pair in a single capsule, high input impedance and a smooth, natural sound character reminiscent of tube amplifiers are ensured. This provides stable and high-quality signal processing.

• R2R Volume Control: Two R2R volume chips from JRC, combined with dedicated operational amplifiers, create a 4-channel balanced volume regulation. This provides precise level control, perfect channel balance, and a wide, clear soundstage.

• Two Gain Modes: Low gain mode offers precise control and extremely low noise for in-ear headphones, while the high mode delivers up to 6.5 W power – enough to drive even the most demanding over-ear headphones with ease.

• Versatile Connectivity: Equipped with 2 headphone outputs (6.35 mm single-ended and 4.4 mm Pentaconn), 2 line inputs, and 2 preamplifier outputs. Use the N7 as a dedicated headphone amplifier or as a high-quality preamplifier for active speakers or power amplifiers.

• Full Aluminum Chassis: Provides optimal heat dissipation and timeless elegance.

• 3D Thermal Architecture: Ensures stable operating conditions for Class A performance.

• 3-inch Display and Multifunction Knob: Intuitive use with real-time display of power and temperature in two colors.

• Aluminum Remote Control: Convenient control directly from the listening position.

• Compact and Aesthetic Design: With clean lines and minimalist aesthetics, the N7 seamlessly blends into modern desk environments while delivering powerful performance.
