Design and Build Quality

From the moment you hold the SRM-D10 II in your hand, its rugged aluminium-alloy shell speaks volumes. At just 450 g and measuring a slender 75 × 32 × 141 mm, this little powerhouse is both robust and refined. The precision-machined casing not only looks sleek but offers superior corrosion resistance, shielding the high-voltage circuits within.

Key design highlights:

• Sturdy aluminium alloy chassis with modern aesthetic
• Compact footprint for easy transport
• Intuitive volume knob calibrated for fine gain control

Audio Performance: Unmatched Clarity and Dynamics

At the heart of the SRM-D10 II lies STAX’s renowned high-voltage electrostatic amplification, delivering 580 V DC bias for astonishing transient response and a truly three-dimensional soundstage. The onboard high-resolution DAC supports up to DSD256 and PCM 384 kHz/32 bit, ensuring your studio-grade files are reproduced with immaculate fidelity.

Highlights of the SRM-D10 II’s sonics:

• Harmonic distortion ≤ 0.025% (1 kHz–10 kHz) for transparent, artefact-free playback
• Gain of 53 dB (450×) to drive even the most demanding PRO-series earspeakers
• Hardware DSD decoding and premium audio-grade capacitors for vivid detail retrieval
• Wide dynamic headroom, allowing both whisper-quiet passages and orchestral climaxes to shine

Power and Portability

Whether you’re connected via USB-C or the 3.5 mm analogue line-in, the SRM-D10 II delivers consistent performance. A versatile supply voltage range (5 V/9 V/12 V/15 V) means you can power it from laptops, battery packs or universal adaptors. Expect around 4.5 hours of playback on analogue input (3.5 hours on digital)—perfect for long flights or train journeys.

Technical snapshot:

• Supply voltage: DC 5 V/9 V/12 V/15 V
