The Beauty of Simplicity

Vintage Tubes, Cutting-edge Sound

The N3Ultra uses a fully-customized operating system that

streamlining to focus solely on audio application.

Creating a device that provides an authentic and minimalist

experience, allowing users to enjoy the new auditory pleasure

brought by the vintage JAN6418 vacuum tubes.

Military-grade NOS Tubes

Applicable to All Analog Outputs

Shock Absorber and Suspension

In-house developed mechanical and

circuitry upgrades minimize microphonic effects

Classic│Modern│Solid-State

Up to Three Timbres in All Analog Outputs

Instead of using the miniature pentode tube as an audio buffer,

N3Ultra adopts Cayin’s Gen3 vacuum tube technology and

employed a two stage timbre circuit for JAN6418:

First Stage:        connect the JAN6418 as a low gain voltage amplifier

Second Stage:  a FET buffer is added to improve the driving capability

of the timbre circuit

By varying the connection method of the screen grid of the

pentode tube, the JAN6418 incorporates local NFB through

the screen grid, resulting in two distinct styles of circuit

response, distortion, and output impedance.

Fun and Versatile Portable Source

Versatile Interface Expand Beyond DAP

Unlocking Numerous Hi-Fi Applications

Customizing with Parametric EQ

Unlocking Numerous Mix and Match Synergy

A 10-bands parametric EQ is specifically designed for the

N3Ultra, offering unlimited sound tuning possibilities.

Allows detailed customization of IEM pairing according to

listening preferences, creating a personalized audio

experience tailored to the user.
