Specification

iBasso PB6 — Quad-Tube, Dual-Mode Portable Balanced Headphone Amplifier

Big drive, switchable tube/solid-state tone, fully balanced architecture.

PB6 employs four military-grade JAN6418 directly-heated pentodes in a fully balanced amplification layout, offering both TUBE and Class AB output modes. The internal 8.4V high-voltage battery pack and optional 12V DC-IN desktop power unlock near desktop-class dynamics on the go. With 3.5mm single-ended / 4.4mm balanced dual inputs and outputs, PB6 fits diverse front ends and delivers serious current for demanding headphones.

JAN6418 ×4 Tubes Fully Balanced Amp TUBE / Class AB Modes 8.4V HV Battery 12V DC-IN Desktop Thrust OP+BUF Topology BUF634A ×4 Buffers NJW1195A 4-Ch Volume High/Low Bandwidth 3.5 & 4.4 Dual I/O

Key Highlights

  • Quad-tube fully balanced stage: Four JAN6418 with anode supply up to 22.5V, APx555-matched for channel consistency. Rich tube timbre with refined texture and depth.
  • Two output flavors: TUBE = JAN6418 voltage gain + BUF634A current drive (smooth, liquid, warm). Class AB = classic OP+BUF headphone amp (high resolution, control, speed).
  • High-energy power system: 8.4V polymer pack improves efficiency and transient delivery; connect 12V DC-IN to unleash desktop-grade headroom and slam.
  • Tunable bandwidth: High-BW for transient snap & detail; Low-BW for a softer, warmer presentation.
  • Precision volume: NJW1195A 4-channel hardware volume, 0.5 dB steps, ultra-low noise floor and perfectly black background; no low-volume channel imbalance.
  • Anti-microphonics & shielding: PORON suspended tube mounts + metal mesh shield to reduce microphonics and block external EMI for cleaner portable listening.
  • Complete I/O: 3.5 mm SE / 4.4 mm balanced inputs + outputs. 3.5-in → 4.4-out enables balanced drive and adds +6 dB gain.
  • Smart LEDs: Multi-color battery/charge indicators (Green: charging / 100–75%, Blue: 75–50%, Red: 50–25%, Red blink: 25–5%, Fast red blink: <5%).

Specifications

Amplifier Topology / Modes TUBE: JAN6418 ×4 + BUF634A ×4; Class AB: OP+BUF
Power Internal 8.4V high-voltage battery pack; 12V DC-IN external power supported
Bandwidth Modes High Bandwidth / Low Bandwidth switchable
Volume Control NJW1195A 4-channel hardware volume, 0.5 dB steps; ultra-low noise
Inputs / Outputs 3.5 mm SE input / output; 4.4 mm balanced input / output (full bidirectional I/O)
Gain (4.4-in → 4.4-out) Class AB: Low +6 dB / High +12 dB; TUBE: Low +8 dB / High +14 dB
Note: 3.5-in → 4.4-out adds an extra +6 dB gain.
Gain (3.5-in → 3.5-out) Class AB: Low +6 dB / High +12 dB; TUBE: Low +9 dB / High +15 dB
Max Output Level (Balanced) 9.5 Vrms (DC-IN); 8.5 Vrms (Battery)
Max Output Power (Balanced) 2300 mW + 2300 mW @ 32 Ω (THD < 1%, DC-IN)
1600 mW + 1600 mW @ 32 Ω (THD < 1%, Battery)
Max Output Level (Single-Ended) 4.6 Vrms (DC-IN); 4.5 Vrms (Battery)
Max Output Power (Single-Ended) 660 mW + 660 mW @ 32 Ω (THD < 1%, DC-IN / Battery)
Frequency Response Class AB: 10 Hz–80 kHz (-0.1 dB); TUBE: 15 Hz–80 kHz (-0.5 dB)
THD+N (typical) Balanced: -112 dB (2 V in, 300 Ω load, Class AB)
Single-Ended: -110 dB (1 V in, 300 Ω load, Class AB)
Dynamic Range Class AB: 125 dB; TUBE: Balanced 116 dB / SE 110 dB
Channel Separation Class AB: Balanced 135 dB / SE 121 dB; TUBE: 100 dB
Output Impedance Balanced 1.2 Ω; Single-Ended 0.5 Ω
Noise Floor (A-wt, High Gain) Balanced 2.3 μV; Single-Ended 1.8 μV
Recommended Headphones Drives mid/high-impedance dynamics and high-impedance/low-sensitivity planars with ease (use DC-IN for peak dynamics & headroom)
Usage tips: Connect 12V DC-IN for higher voltage swing and maximum thrust. 3.5-in → 4.4-out enables balanced drive with an extra +6 dB gain. To minimize tube microphonics, avoid strong vibration and keep distance from strong EMI sources; switch to Class AB mode if needed.
