Portable fully balanced tube headphone amplifier

The iBasso PB6 Macaw is a flagship portable headphone amplifier that delivers desktop-grade performance in your pocket. Designed for a fully balanced 4-channel architecture, it features four military-grade Raytheon JAN6418 pentode vacuum tubes. With dual output modes (Tube and Class AB), it delivers rich, warm harmonies or clean, dynamic clarity, depending on preference. The 22.5V high-voltage drive provides ample distortion threshold and robust sound, while the 32Ω 2300mW + 2300mW output power easily drives even the most demanding headphones.

Designed for versatility, the PB6 Macaw offers both 3.5mm single-ended and 4.4mm balanced input/output options. Its compact aluminum housing is elegant yet durable, designed for portable use without sacrificing audio fidelity. The amplifier supports 12 V DC-IN external power supply, making it ideal for desktop configurations. Whether IEMs or full-size headphones are connected, the PB6 delivers stable, high-quality signal transmission in all formats.

It is designed for audiophiles and ardent music fans who want the warmth of the tube on the go. The PB6 Macaw is a rare blend of portability and uncompromising sound. Perfect for those who want to explore the finer points of tube reinforcement without being tied to a table. Box contents: PB6 Macaw amplifier, two audio cables, USB charging cable, soft case.
