The Head Box DS3 B is a headphone amplifier from Pro-Ject, built with genuinely substantial output across a range of headphone impedances. The Head Box DS3 B brings Pro-Ject's considered engineering to a dedicated desktop headphone amplification format.
Key specs that matter
Maximum power reaches a substantial 1,500mW RMS per channel into 32 ohms, dropping to 560mW into 300 ohms - genuinely strong figures across this impedance range. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Gain is 12dBu. Total harmonic distortion is a low 0.002% at 1V RMS into 300 ohms, with signal-to-noise ratio exceeding 118dB, and output impedance over 8 ohms. At 206 x 70 x 194mm and 1.43kg, the Head Box DS3 B maintains a genuinely manageable desktop chassis.
Sound and use context
Expect substantial, clean amplification reflecting the strong over-118dB signal-to-noise and low 0.002% distortion figures, with the 1,500mW output at 32 ohms providing genuine dynamic headroom for a wide variety of headphones.
Pairing
The substantial 1,500mW output at 32 ohms and 560mW at 300 ohms handles a genuinely wide range of headphone impedances directly.
Alternatives
Pro-Ject's own Head Box S2 Digital and Head Box S3 B sit within the same broader headphone amplifier catalogue, worth comparing directly to find the right Pro-Ject tier. 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.
