In my review of the RME ADI‑2 DAC, I emphasized how RME successfully distilled the strengths of the ADI‑2 Pro into a more audiophile-focused, streamlined package — at roughly €999 — without sacrificing performance. Inside its sleek all-black chassis beats an upgraded femtosecond-accurate SteadyClock, delivering astonishing precision. The standout feature is its dedicated low-noise 3.5 mm IEM output, which achieves benchmark-level silence, while the main headphone output handles everything from sensitive buds to full-size cans with ease.
On the front panel, the DAC includes easily dimmable or fully off display lights — ideal for minimizing distractions — plus a valuable remote that controls power, volume, input, and DSP functions . The rear I/O swaps the ADI‑2 Pro’s analog-in conversion section for user-friendly RCA line outputs, balanced XLR out, and three digital inputs (USB, optical, coax) .
Inside, the ADI‑2 loses the A/D hardware and one AK4490 DAC chip but remains internally fully balanced while benefiting from improved jitter handling. DSP-wise, it offers a powerful 5-band parametric EQ, front-panel bass/treble controls, and individually adjustable gain and shelving/peak filters — perfect for headphone tuning and room correction.
Compared to its Pro sibling, the ADI‑2 DAC runs cooler with a sleeker build, drops analog inputs, and adds useful features like the remote and dedicated IEM jack, while inheriting much of the Pro’s sonic performance and menu flexibility. In short, it’s an impeccably engineered, feature-rich DAC/head‑amp combo — offering pro-grade precision, ultra-low noise, and rich DSP options — in a more elegant, home-friendly design.
