Your phone is a remarkable piece of technology, but it was never designed to be a serious music player. Its audio circuit shares space with a camera, a modem, a GPS receiver, and a dozen other systems all competing for power and bandwidth.

A dedicated digital audio player removes that compromise entirely: a device built around a single purpose, with a DAC and amplifier chosen for sonic performance rather than miniaturisation and cost-cutting.

Whether you are a serious listener building a lossless library or a DJ/producer looking for a high-quality playback solution for your reference headphones, these five DAPs span the price ladder from accessible to aspirational, and all carry Hi-Res Audio certification to back up their credentials.

FiiO has earned a formidable reputation for delivering high-end audio components at prices that consistently undercut the competition, and the M23 is arguably the clearest expression of that philosophy.

The pairing of AKM's AK4191EQ and AK4499EX is a flagship DAC combination: the two chips operate in a fully separate digital/analogue architecture with DWA Routing Technology to minimise noise at the conversion stage.

The THX AAA 78+ amplification stage delivers four-way balanced output, and the M23's dedicated power-in USB-C port is a genuinely clever engineering solution: connecting it unlocks Super High Gain Desktop Mode, bypassing the battery entirely to deliver over 1,000mW per channel for high-impedance over-ear headphones.

The substantial 5,500mAh battery handles up to ten hours of lossless balanced playback on its own, with 30W fast charging retrieving a significant charge in under an hour. The 5.5-inch display is large by DAP standards, making album browsing and streaming app navigation genuinely comfortable.

At around £800, the M23 sits in a premium bracket, but the combination of flagship DAC hardware, serious amplification, and a well-judged feature set makes it the strongest all-round proposition at its price point.

The result of a collaboration between Hidizs and audio retailer Linsoul Audio, the AP80 Pro Max is remarkable value for the technology packed into its CNC-machined aluminium frame.

The dual ES9219C DAC architecture delivers measurable performance well above its price bracket, with a dynamic range of up to 122dB and THD+N of just 0.0005%. Both single-ended and balanced outputs are present despite the player's compact 82.8 x 51 x 15.5mm footprint, and the 4.4mm balanced output puts out a respectable 190mW per channel, more than sufficient for most IEMs and efficient headphones.

Connectivity is comprehensive: Bluetooth 5.1 with LDAC, UAT, aptX, and AAC sits alongside 2.4GHz Wi-Fi for direct streaming from Tidal, Qobuz, and DLNA sources. The device runs HiBy's dedicated HiByOS rather than full Android, which keeps the interface fast and responsive while offering the MSEB sound tuning system for personalised EQ.

Both Hi-Res Audio and Hi-Res Wireless certifications are printed on the rear panel. No internal storage is included, so factor in the cost of a microSD card, but support extends up to 2TB.

At around £140, this is the most accessible entry point to genuinely certified hi-res audio playback on the market.

Shanling has been building audio equipment since 1988, graduating from high-end CD players and valve amplifiers to become one of the most respected names in portable Hi-Fi.

The M3 Plus, unveiled at High End Munich 2025, is the strongest entry in their M3 series to date. The quad-DAC configuration centres on four Cirrus Logic CS43198 chips, the same flagship chip Astell & Kern uses in its A&norma line, delivering support for PCM up to 32bit/768kHz and native DSD512.

The 4.4mm balanced output is where the M3 Plus really distinguishes itself at this price: 800mW into 32 ohms is genuinely serious power, capable of driving demanding over-ear headphones without compromise.

Open Android 13 provides access to Tidal, Qobuz, Apple Music, and Spotify, while Shanling's proprietary AGLO (Android Global Lossless Output) framework bypasses Android's native sample rate conversion to ensure bit-perfect playback regardless of which app is running.

The precision-milled aluminium chassis comes in three colourways and weighs 205g: substantial enough to feel premium, compact enough at 115 x 70 x 18mm to slip into a jacket pocket. European buyers should note that Amazon.de stock may vary; Linsoul DE is the authorised EU distributor.

South Korean audio specialists Astell & Kern have been setting the benchmark for portable hi-res playback since their first players appeared over a decade ago, and the A&norma SR35 represents the point at which their flagship technology becomes genuinely attainable.

The quad CS43198 DAC arrangement is paired with New Generation AMP circuitry previously exclusive to the company's top-tier A&ultima series, and the result is a 130dB signal-to-noise ratio: a figure that puts the SR35 ahead of most competitors at its price.

The TERATON ALPHA platform, Astell & Kern's proprietary power noise reduction and amplification architecture, ensures the DAC has a consistently clean power supply throughout.

A dual/quad DAC switching mode lets users trade battery life for soundstage width depending on the listening context, extending what is already an impressive 20-hour battery life further still. Roon Ready certification makes it a seamless fit for anyone running a home Roon library.

The angled display and chunky volume wheel are unmistakably A&K in design; the balanced 4.4mm output delivers up to 6Vrms. Available in Charcoal Grey and awarded What Hi-Fi? 2025's top portable player honour, the SR35 is the definitive step up from mid-range Hi-Fi.

There is something quietly satisfying about the fact that Sony, the company that invented the portable music player with the original Walkman in 1979, still makes some of the best ones around.

The NW-ZX707 is built around a philosophy of high-quality component selection rather than headline DAC chip specifications: the circuit board separates the audio block from the power and digital sections entirely to eliminate interference, while custom FT CAP3 capacitors tuned specifically by Sony engineers handle bypass capacitance across the audio power supply.

The S-Master HX digital amplifier supports native DSD playback up to 11.2MHz and PCM up to 32bit/384kHz with low-jitter precision from dual quartz oscillators running at 44.1kHz and 48kHz reference rates. A 4.4mm balanced output delivers clean signal separation, and the 5.0-inch touchscreen runs Android 11 for full streaming app support.

Battery life reaches 25 hours at standard resolution, dropping to around 18 hours with DSD or high-resolution content. At 64GB internal storage with microSD expansion, there is room for a substantial lossless library.

The aluminium chassis is understated and robust, the kind of device that rewards daily use without demanding attention for itself. For listeners who want established pedigree, a clearly defined sonic character, and genuinely premium build at under £800, the ZX707 remains an outstanding choice.

The FiiO M23 is the one to beat: flagship DAC hardware, serious amplification power, and a feature set that covers every use case from streaming to lossless library playback.

If budget is a consideration without wanting to compromise on Hi-Res certification and genuine balanced output, the Hidizs AP80 Pro Max delivers a remarkable amount of performance for its price.
