Four Tube Design for Rich and Natural Sound

The PB6 uses four JAN6418 vacuum tubes arranged in a fully balanced configuration. This design produces a warm, natural, and expressive sound with smooth mids, rich harmonics, and excellent musicality.

Each tube is carefully matched to ensure consistent performance and accurate channel balance.

Dual Output Modes for Flexible Sound Signature

The PB6 offers two different output modes
Tube mode delivers a warm, smooth, and analog style sound
Class AB mode provides higher resolution, stronger dynamics, and cleaner output

This allows users to switch between different sound profiles based on their preference.

Powerful Output for Demanding Headphones

With output power reaching up to 2300mW per channel at 32 ohms, the PB6 can easily drive full size headphones. When connected to an external 12V power supply, it unlocks its full performance potential.

Advanced Power System for Clean Performance

The PB6 uses a high voltage battery system combined with efficient power management. This reduces noise and ensures stable power delivery, resulting in a cleaner and more dynamic sound.

Precision Volume Control for Accurate Listening

The built in NJW1195A volume control chip allows fine adjustments in 0.5dB steps. This ensures precise volume control with perfect channel balance and reduced background noise.

Customizable Sound with Bandwidth Selection

Users can choose between high bandwidth mode for better detail and fast transients or low bandwidth mode for a smoother and warmer presentation. This adds flexibility to tailor the listening experience.

Reduced Microphonics with Advanced Damping

The tubes are suspended using PORON damping material to minimize vibration and microphonic effects. Additional shielding helps reduce external interference for stable performance.

Versatile Connectivity Options

The PB6 supports both 3.5mm and 4.4mm inputs and outputs. This allows it to work with a wide range of audio sources and headphones, including converting single ended input to balanced output.
