Experience The Pure Analog Magic:-

iBasso PB5 brings a purely analog sound with its dual hybrid tube design. It brings a charming sound with a rich tone and clear dynamics. The high-end NuTubes add a rich flavor to the sound bringing lovely vocals and a magical tone.

Dual NuTube 6P1 Tubes:-

Developed by KORG and Noritake, the 6th gen NuTube on the iBasso PB5 operates exactly as a conventional triode vacuum tube and creates the same rich and dynamic overtones that are appreciated in a desktop tube amplifier. NuTube achieves substantial power savings with a high-efficiency design. Voltage amplification is also achieved with the NuTube, which results in a captivating and distinctive vacuum tube sound.

High-Efficiency Power Circuit:-

iBasso PB5 adopts a high-efficiency power circuit. The amplifier utilizes six batteries for a robust power supply system. The NuTubes are powered by two batteries while the other 4 batteries provide power to the secondary amplifier. With this high-efficiency circuit, the output is clean and crisp with no audible noise or power interference.

Precise Volume Adjustment:-

iBasso PB5 features extremely diminutive 24-position, 4-section stepped attenuator. It provides optimal analog volume control that greatly enhances the ability to showcase distinctive analog tones and provides excellently precise volume adjustment for both channels.

Tremendously Powerful:-

Along with the rich tone, we also have high-power output from the iBasso PB5. It has a strong output power rating of up to 1700mW per channel at 32Ω of impedance load. It can drive high-power requiring IEMs and Headphones without breaking a sweat.
