By combining military-grade vacuum tube warmth with the precision of solid-state Class AB amplification, the PB6 MACAW delivers an unparalleled listening experience for both demanding full-sized headphones and sensitive IEMs.

• Tunable Bandwidth & Gain: Tailor your audio to your preference. Use Low-Bandwidth for a soft, classic tube tone or High-Bandwidth for enhanced dynamics and fast transients. Two-level adjustable gain ensures compatibility with a wide range of gear.

• Desktop-Level Drive: With a massive 2300mW per channel output (at 32Ω), this amplifier effortlessly drives even the most power-hungry full-sized headphones. Support for an external 12V DC input allows for desktop-grade performance at home.
