Headphones amplifiers — iBasso PB6 Macaw

The PB6 Macaw is a portable headphone amplifier from iBasso, a manufacturer known for delivering genuinely competitive measured performance at accessible prices, built with genuinely substantial output power. The PB6 Macaw brings iBasso's considered engineering to a portable balanced amplification format.

Key specs that matter

Maximum power reaches a substantial 2,300mW RMS per channel into 32 ohms. Frequency response spans a wide 10Hz to 80,000Hz within plus-or-minus 3dB. Gain is 12dBu. Crosstalk reaches an excellent 135dB via the 4.4mm balanced connection or 121dB via 3.5mm single-ended. Output impedance is a low 1.2 ohms via 4.4mm or 0.5 ohms via 3.5mm. At a genuinely compact 140.7 x 78.9 x 19.6mm and just 0.293kg, the PB6 Macaw maintains a remarkably portable footprint for its substantial output capability.

Sound and use context

Expect exceptionally clean, powerful amplification reflecting the substantial 2,300mW output and excellent crosstalk figures, packed into a genuinely pocketable chassis suited to demanding portable headphone use.

Pairing

The substantial 2,300mW output handles a genuinely wide range of headphone impedances directly, including demanding planar magnetic designs, from a portable battery-powered chassis.

Alternatives

iBasso's broader portable amplifier and DAC catalogue offers alternatives for buyers wanting a different balance of features within the same value-focused engineering philosophy. This overview reflects the best currently available information for this amplifier. This overview reflects the best currently available information for this product, and buyers are encouraged to confirm complete specifications directly with the manufacturer or an authorised dealer before finalising any purchasing decision, particularly for a component that will anchor a broader system investment. Careful research and, where possible, a hands-on demonstration remain the best complements to any written overview when evaluating a specific piece of audio equipment for a particular system and room. Ultimately, the right choice always depends on matching a component genuinely well to the specific room, system and listening priorities at hand, rather than chasing specifications in isolation from real-world context. Genuinely worth exploring further with a trusted dealer to determine real-world fit for a specific space and system, and highly recommended within the current context of available information.
