Description

The N7 DAC Edition (N7D) is a compact, fully discrete Class-A headphone amplifier and USB DAC. With a twin JFET input, fully balanced four-channel R2R volume control, dual-level Class-A bias, dual gain settings, and preamp functionality, it delivers authoritative performance and a musical, high-resolution sound – powering all kinds of headphones and IEMs with ease.

Digital Audio Hub

All-in-One – Digital & Analog

Equipped with two Cirrus Logic CS43198 DACs, the N7D supports PCM up to 384 kHz and DSD256. USB-C enables plug-and-play with PC, Mac, iOS, or Android. Additionally, RCA/XLR analog inputs and outputs are available, allowing the N7D to excel both as a headphone amplifier and as a preamp.

Twin JFET

Tube-Like Sound

The twin JFET input stage provides smooth, natural sonic characteristics. Thanks to perfectly matched pairs, voltage remains stable and the sound remains harmonious – the ideal basis for refined amplification stages.

Class-A Dual-Level Bias

Two Stages, One Goal: Warmth & Fullness

The specially designed dual-level Class-A bias keeps the amplifier running in pure Class-A operation. The result: silky-smooth, full-bodied sound with natural warmth and organic tonality.

R2R Electronic Volume

Precision & Balance

Two R2R volume control chips from JRC, combined with dedicated op-amps, form a fully balanced four-channel control. This ensures precise regulation, perfect channel balance, wide soundstage, and accurate imaging.

Dual-Gain Settings

From IEMs to Over-Ears

Two gain levels provide optimal adaptability: low gain for sensitive IEMs with perfect control, high gain with up to 6.5 W output for demanding over-ear headphones.

Rich Connectivity

More Than Just a Headphone Amplifier

With USB-C, two line inputs, two headphone outputs, and two preamp outputs, the N7D offers flexible connectivity – serving both as a headphone amplifier and as a preamp for active speakers or power amps.

Full Aluminum Chassis

Stable Class-A Thermal Performance

The Class-A amplifier’s transistors operate continuously in the linear region, generating constant heat. A specially designed 3D thermal architecture ensures even cooling and guarantees stable, uncompromised Class-A sound – powerful, balanced, and audiophile.

3-Inch Display

One Knob, Full Control

A multifunction knob controls all functions – bias adjustment, gain switching, and headphone/preamp modes. A remote control is also included for convenient operation from a distance.

Better UI

Intuitive & Clear

A new user interface with clear indicators: two colors display current and temperature in real time. Simple, modern, and easy to read.

Aesthetic Design

Minimalist & Timeless
