The Beauty of Simplicity
The N3Ultra uses a fully-customized operating system streamlining to focus solely on audio application. Crafted with intention, the device provides an authentic and minimalist experience, allowing users to enjoy the new auditory pleasure brought by the vintage JAN6418 vacuum tubes.
Shock Absorber and Suspension
Custom-molded shock absorption Silicon housing to hold and shield the JAN6418 vacuum tube. Designed pairs of suspension pins into the CNC aluminum frame of N3Ultra, the JAN6418 is hanged vertically with suspension effect.
Cayin integrated the miniature vacuum tube with the body frame, achieving multi-directional stress relief for the tube's filament. The DAP offers enhanced stability by introducing an appropriate amount of inter-stage loop NFB to inhibit the closed-loop gain. FET is employed to control the power supply of the vacuum tube and stabilize the working current of the tube filament.
Classic. Modern. Solid-State
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.
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.
Dual Line Out
On top of a dedicated 3.5mm single-ended line out, the 4.4mm balanced output can be configured into Phone out or Line out.
Maximum compatibility with configurable output levels
- 3.5mm: 2.1V (High), 1.6V (Mid), 1.0V (Low)
- 4.4mm: 4.2V (High), 3.2V (Mid), 2.0V (Low)
This enables users to connect the N3Ultra to a variety of portable desktop and home audio devices.
Clean and Unamplified
Line Out is fixed voltage line level output bypassing volume control and headphone amplification. This serves as high quality source for headphone amplifier (portable or desktop) and integrated amplifier home audio systems.
Applicability of Tube Timbres
Solid-State, Classic tube and Modern tube timbres are available to all analog outputs, including 3.5mm and 4.4mm headphone and line output options.
Versatile Interface Expands Beyond DAP
DAC/Digital Transport
- USB Audio (Input/Output) - USB-C
- S/PDIF Coaxial (Output) - USB-C embedded
Amplifier/Active Speakers (Line Out)
- 3.5mm Single-ended
- 4.4mm Balanced (Shared)
Headphone
- 3.5mm Single-ended
- 4.4mm Balanced (Shared)
Customizing with Parametric EQ
A 10-bands parametric EQ is specifically designed for the N3Ultra, offering unlimited sound tuning possibilities. This allows detailed customization of IEM pairing according to listening preferences, creating a personalized audio experience tailored to the user.
Digital Audio with Fully Differential Output
Dual AK4493S DAC chipset operates in Mono mode for fully differential output. Independent DAC chips and analog audio circuits for each channel minimize crosstalk, enhancing the audio clarity and stereo separation.
Professional Precision
- Employs JRC NJW1195A 4-channel volume controller
- Employs (x2) Accusilicon AS318 Femtosecond Oscillators
- Low noise distortion resistance ladder analog volume chip commonly used in audiophile preamp
- Ultra low phase noise (-100dBC) maintaining signal conversion accuracy with significantly lower jitter
- 4-channel in one integrated controller offers high precision and lower power consumption
- Minimize digital artifact and enhance the musicality and naturalness of playback
Fast Charging, Long Playback Duration
The N3Ultra employs a hefty 3.85V 4500mAH Lithium battery with a carefully tuned power management system. Continuous playback is available up to 11.8 hours with 3.5mm SE connected IEM in solid-state timbre, and 7.6 hours with 4.4mm balanced connected IEM in vacuum tube timbre. Recharge quickly with QC3.0 which yields an 80% charge in about 1 hour!
