Dac: A Complete Buyer's Guide
Before you buy a DAC, you need to know what you're connecting it to — because getting that wrong is the most expensive mistake you can make.
Buying a DAC is one of those decisions that rewards clarity — knowing what you actually need before you spend anything. The market ranges from a twenty-quid dongle that slots into a phone to five-figure separates for dedicated listening rooms, and the difference between them is not always as large as the price suggests. This guide will help you cut through the noise and spend your money where it actually counts.
Start with What You're Connecting It To
The most important question when buying a DAC is what you'll be connecting it to — both as a source (what sends it the digital signal) and as an output (what it feeds downstream). Getting this wrong is the most common purchasing mistake.
- Computer/laptop → headphones: You need a desktop DAC/amp combo with a headphone output. USB-A or USB-C connection to your computer, 3.5mm or 6.35mm jack output for headphones. This is the most popular category and the most competitive — there are excellent options from around £70.
- Computer/laptop → amplifier and speakers: You need a standalone desktop DAC with RCA or XLR outputs. It will sit in your signal chain between computer and amplifier.
- Phone → headphones on the go: You need a portable dongle DAC. These plug into a USB-C port and offer a 3.5mm headphone jack. Options from FiiO, Hidizs, and Cayin start well under £50.
- Existing hi-fi system (CD player, TV, streaming box): You need a component DAC with optical (TOSLINK) or coaxial digital inputs.
Setting a Realistic Budget
Genuine sonic performance is accessible at modest prices. Rough budget tiers:
| Budget | What to expect |
|---|---|
| Under £50 | Dongles and entry-level desktop units. Audibly better than most laptop outputs. Good enough for most listeners. |
| £80–200 | The performance sweet spot. Units like the iFi Zen DAC, Topping E30, and FiiO K7 perform admirably and lack nothing essential. |
| £200–500 | Higher build quality, better output stages, often balanced outputs. Worth it if driving high-impedance headphones or a demanding amplifier. |
| £500+ | Diminishing returns become significant. Worth considering if the rest of your system justifies it — otherwise, the £200 saved is better spent elsewhere. |
The Specifications That Actually Matter
DAC marketing is full of impressive-sounding numbers. Here's what genuinely matters and what to take with a pinch of salt:
- Output impedance — lower is better, particularly if driving sensitive headphones. Aim for under 1 ohm for in-ear monitors.
- Output power (headphone amp stage) — if you're driving high-impedance headphones (250 ohm, 300 ohm), you need adequate output power. Check the headphone's specification and match accordingly.
- THD+N (Total Harmonic Distortion plus Noise) — a measure of distortion. Anything below 0.01% is inaudible in practice; many budget units achieve 0.001% or lower.
- Supported formats — if you plan to use hi-res audio files, ensure the unit supports 24-bit/192kHz or MQA if relevant. In practice, most buyers will never use anything above 24-bit/96kHz.
Ignore signal-to-noise ratio (SNR) figures above 110dB — the practical difference is academic. Similarly, dynamic range figures above 100dB exceed what most headphones and speakers can resolve.
Brands Worth Knowing
The market at sensible price points is dominated by a handful of manufacturers who offer consistently reliable performance:
- iFi Audio (British) — known for clean design, good measurements, and excellent value. The Zen DAC Signature is a popular mid-range desktop choice.
- FiiO — the most consistently recommended brand for portable and budget desktop units. The K7 desktop DAC/amp is a consistent recommendation around the £200 mark.
- Topping and SMSL — Chinese brands with strong measurement performance at accessible prices. The Topping E30 II and SMSL SU-1 are well-regarded budget options.
- Cambridge Audio (British) — the DacMagic series has a long and respected track record in desktop territory.
- Chord Electronics (British) — the premium end. The Hugo 2 and DAVE are regarded among the best portable and desktop DACs available, at commensurately high prices.
What to Avoid When Buying
A few common pitfalls:
- Buying before you've identified the bottleneck. If your current setup sounds poor, the problem may be your headphones or speakers, not the converter. Rule out the obvious first.
- Over-speccing the converter relative to the rest of the system. A £400 unit feeding £80 speakers is poor allocation of funds.
- Chasing MQA support. MQA (Master Quality Authenticated) was a proprietary hi-res audio format that has now been largely abandoned following Meridian's sale of the technology. Paying a premium for MQA support is not recommended.
The Bottom Line
Get clear on what you need it to connect to, set a sensible budget, and choose from the established brands.
