Nutube 6P1 Application
Supports both single-ended 3.5mm and balanced 4.4mm PO/LO outputs.
Each output can toggle between tube and solid-state modes.

Classic丨Modern丨SS 

Classic：
No global negative feedback; each stage uses local feedback.
Tube amplification introduces higher total harmonic distortion (THD).
Rich harmonic texture delivers a warm, nostalgic sonic flavor — classic “tube sound.”

Modern：
Introduces global negative feedback to define total gain.
THD is significantly reduced.
Harmonically cleaner, quieter background while preserving the warmth of tubes.
Yields a sweet, clear, and delicate modern tube audio signature.

Solid-state：
Based on precision-tuned op-amp ICs and peripheral circuits.
Offers neutral tonality, fast transients, and highly accurate audio reproduction.
Ideal for listening to music with its original, uncolored character.

Dual AKM AK4493SEQ DAC
Equipped with dual AK4493SEQ DACs, each operating in mono mode.
Left and right channels are decoded separately for lower crosstalk and better channel separation.

16-Core XMOS XU316 Processor
Employs the latest generation XMOS XU316 USB Audio solution for high-performance digital processing.

Triple Power Supply Modes
Built-in 2000mAh lithium battery provides up to 4.7 hours of battery-powered use. Also supports USB power from the external device (without charging the battery), as well as external DC power supply for increased output power.

Compatible with QC/PD fast charging.

Hyper Mode
A specialized feature designed for headphone usage under DC power supply. Increases static operating current and voltage for enhanced audio performance.

Balanced: 1000mW + 1000mW @ 32Ω; 1170mW + 1170mW @ 16Ω
Single-ended: 420mW + 420mW @ 32Ω; 610mW + 610mW @ 16Ω

Magnetic Back Design
Magnetic rear panel allows seamless attachment to smartphones.
Includes a custom Cayin leather case — hand-stitched, supple leather, precise cutouts, and magnetic back for secure attachment.
Comes with a L-shaped USB cable, ergonomically angled to avoid hand obstruction.

S/PDIF Input/Output
