Built-in parametric EQ: correct a headphone's tuning in hardware, for any source
See RME ADI-2 DAC FS Ultra-Fidelity PCM/D… on AmazonShort version: the RME ADI-2 DAC FS is a premium DAC and headphone amp from a pro-audio maker, and its standout feature is control: a built-in parametric EQ that works for every source, two headphone outputs (one optimised for IEMs), a display, a remote and deep settings. If you’ll use those tools, it’s an endgame purchase. If you only want clean conversion, much cheaper DACs get close.
Buy it if you want to EQ your headphones properly, use both IEMs and full-size headphones, or want one high-end box for years. Skip it if you don’t plan to use EQ; a Topping DX5 covers clean conversion and amplification for much less.
Availability: the RME ADI-2 DAC FS is not currently listed in stock new on Amazon US, and no successor model listing was found. Check RME’s own dealer list for stock.

What it does well
Hardware EQ. Most headphones benefit from small corrections. The ADI-2’s parametric EQ applies them in the device, so they work with every source: computer, streamer, TV or phone.
One box for IEMs and headphones. A dedicated low-noise IEM output avoids the background hiss sensitive IEMs can pick up from powerful amps, while the main output drives full-size headphones.
Measured performance and build. It comes from a professional audio-interface maker, and it’s built and supported accordingly.
Where it falls short
Price versus cheaper DACs. Conversion quality is excellent, but well-designed budget DACs are already transparent for most listeners. You pay mostly for features and build.
Learning curve. The menus are deep. Expect to spend time setting it up.
How it compares
| Device | Choose it if… |
|---|---|
| RME ADI-2 DAC FS | You want hardware EQ and pro-level control |
| Topping DX5 | You want clean conversion and a balanced amp for much less |
| Topping D90 III Sabre | You want a fully balanced desktop DAC with Bluetooth LDAC |
| FiiO BTR7 | You want a portable Bluetooth DAC/amp with a 4.4mm balanced output |

Verdict
The ADI-2 DAC FS is the DAC to buy if you want control, not just conversion. If you won’t use the EQ and settings, put the money towards better headphones instead.

Frequently Asked Questions
Is the RME ADI-2 DAC FS worth it?
If you'll use its parametric EQ and features, yes: it lets you tune any headphone in hardware, for every source. If you only want clean conversion, cheaper DACs measure close enough that the extra cost is hard to justify.
Can the ADI-2 DAC drive headphones directly?
Yes. It has two headphone outputs, including one optimised for sensitive IEMs, so you don't need a separate amp for most headphones.
What's the ADI-2's parametric EQ for?
Correcting a headphone's frequency response towards a target you prefer, such as Harman. Because it's in hardware, it applies to every source, not just one app.
