There is no universal winner. Choose Sony’s NW-WM1ZM2 if you want the maker’s rich, full-bodied and spacious presentation. Choose Astell&Kern’s SP3000T if you want a highly specified flagship with multiple balanced outputs and the cohesive, balanced and authoritative presentation described by What Hi-Fi?. The better-sounding player depends on your headphones, preferred tonal balance, output requirements and tolerance for luxury pricing.
Quick verdict
- Best fit for a rich, spacious sound: Sony NW-WM1ZM2. Sony positions its S-Master HX player, power supply, capacitors, solder and gold-plated oxygen-free-copper chassis around a full-bodied presentation, clearer vocals, tighter bass and a wider sound space.
- Best fit for output flexibility and a highly specified design: Astell&Kern SP3000T. Its published architecture uses dual AKM AK4191 modulators and dual AK4499EX DACs, with separate unbalanced and balanced output specifications.
- Best documented connector choice: the SP3000 family. What Hi-Fi? lists 3.5mm, 2.5mm balanced and 4.4mm outputs for the SP3000, while the SP3000T specification cites 3.3Vrms unbalanced and 6.3Vrms balanced output.
- Best objective answer: neither. No controlled blind test using the exact NW-WM1ZM2 and SP3000T with the same headphones establishes one as universally more accurate.
What you are comparing
Sony NW-WM1ZM2 Walkman
The NW-WM1ZM2 is Sony’s premium digital audio player (DAP). It uses Sony’s S-Master HX digital amplification and supports Native DSD playback and high-power balanced output. Its most distinctive physical feature is a gold-plated oxygen-free-copper chassis. Sony describes the power-supply design, capacitors, solder and chassis materials as choices intended to reduce noise and improve vocal clarity, bass control and the sense of space.
Those descriptions are manufacturer design goals, not the result of a published, controlled comparison against the Astell&Kern. They are still useful when you are deciding whether Sony’s stated voicing matches your taste: the company’s language consistently points toward weight, body and spaciousness rather than an aggressively analytical balance.

Astell&Kern SP3000T
The SP3000T is Astell&Kern’s flagship-style player in the comparison. The official specification lists dual AKM AK4191 modulators and dual AK4499EX DACs, PCM playback up to 32-bit/768kHz and Native DSD512. It specifies 3.3Vrms from the unbalanced output and 6.3Vrms from the balanced output.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals.

Independent descriptions add useful context but should not be confused with a lab verdict. What Hi-Fi?’s 2026 guide describes the SP3000 as cohesive, balanced, authoritative and muscular, and says, “The organisation of information is excellent.” TechRadar’s 2026 guide characterizes the SP3000 as a premium design with six DACs and independent balanced and unbalanced circuits, while warning that its price limits value. Those assessments concern the SP3000 model named by the publications; do not automatically treat every SP3000 observation as a measured claim about the SP3000T.

How the two sound descriptions differ
Sony: body, warmth and space
Sony’s own description is the clearest guide to the NW-WM1ZM2’s intended character. “Rich,” “full-bodied” and “spacious” suggest a presentation that gives instruments physical weight and leaves more apparent room around voices and recordings. Sony also links its component choices to clearer vocals and tighter bass.
This profile can suit headphones that are lean, bright or highly explicit, because additional body can make vocals and acoustic instruments feel less thin. It can also appeal to listeners who prefer a broad, enveloping stage over a relentlessly dissected presentation. The same qualities may be less attractive if your headphones are already warm or bass-heavy and you want maximum restraint.

What Hi-Fi?’s language points in a different direction. “Cohesive” implies that sections of a recording lock together naturally; “balanced” indicates an even tonal impression; “authoritative” and “muscular” suggest control and impact rather than a lightweight sound. This is a reviewer’s listening description, not an Astell&Kern promise that every headphone will sound identical.

The SP3000T’s separate conversion and output architecture, plus its higher published balanced voltage, gives you a strong platform for demanding headphones and for listeners who want to choose among several cable standards. A technically elaborate signal path does not guarantee that you will prefer its voicing, however. Your headphone’s own frequency response remains the largest audible variable.
Why the descriptions do not produce an objective winner
Neither set of language is a standardized measurement. Sony’s statements are product-positioning claims, while the SP3000 assessment is an independent listening report on the SP3000. There is no cited blind, same-headphone test of the exact NW-WM1ZM2 against the SP3000T. Treat “better” as a system-matching decision, not as a universal ranking.
Match the player to your headphones
Start with the headphones or in-ear monitors you already own, not with the player’s component count. Write down their impedance, sensitivity, connector and tonal balance. Then use this sequence:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute- Identify the load. High-impedance headphones generally need more voltage; inefficient planar headphones can also demand substantial power. Sensitive IEMs may expose hiss or channel imbalance more readily than full-size headphones.
- Choose the tonal direction. If your headphones sound thin, forward or bright, Sony’s stated rich and full-bodied target may be the more natural audition. If they are already warm and you want a controlled, balanced presentation, the SP3000T may be the more convincing match.
- Check the cable you actually use. The SP3000 family’s listed 3.5mm, 2.5mm and 4.4mm options reduce the need for adapters. Verify the exact socket and wiring of your cable before buying; a balanced plug is not automatically interchangeable across every product.
- Reserve balanced output for a real need. Balanced operation can provide more output headroom when the player and headphone are designed for it, but it does not inherently make every recording sound better. Do not connect a single-ended headphone cable to a balanced socket through an unsafe adapter.
- Audition at matched volume. A slightly louder player can seem more detailed or dynamic. Compare at the same comfortable level, with the same files and the same headphone, before deciding that one has superior resolution.
Output power and connector flexibility
The SP3000T publishes the clearest numerical advantage in the supplied specifications: 3.3Vrms unbalanced and 6.3Vrms balanced. That balanced figure gives you more voltage headroom for headphones that need it, provided your cable and headphones support a properly wired balanced connection.

For the SP3000, What Hi-Fi? lists three analogue output formats: 3.5mm single-ended, 2.5mm balanced and 4.4mm balanced. This is valuable if your collection includes multiple cable standards or if you move between IEMs and full-size headphones. The available connector set is a practical advantage, independent of whether you prefer the sound.
Sony’s supplied specifications confirm balanced and high-power capability for the NW-WM1ZM2 but do not provide a directly comparable voltage figure here. That means you should check the current regional manual and the impedance and sensitivity requirements of your headphones before assuming either player will drive a particularly difficult load better.
High-resolution formats and DAC architecture
What both approaches mean in practice
Both players are designed for high-resolution libraries and Native DSD playback. In normal listening, format support matters only when your files, software and headphones can use it. A 32-bit/768kHz file will not sound better merely because a player accepts it, and converting a recording to a higher number does not restore information that was never captured.
Where the SP3000T has the clearer ceiling
Astell&Kern’s cited SP3000T ceiling is PCM up to 32-bit/768kHz and Native DSD512. The dual AKM AK4191 modulator and dual AK4499EX DAC design is a concrete architectural specification, not a guarantee of a preferred tonal balance.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
What Sony emphasizes instead
Sony emphasizes its S-Master HX digital amplification and the way its power supply, capacitors, solder and chassis are intended to reduce noise and improve the listening presentation. The supplied Sony pages confirm Native DSD support but do not establish a matching maximum PCM and DSD figure for this comparison, so do not infer one.
Storage, library size and travel
What Hi-Fi?’s 2026 SP3000 listing gives the player 256GB of internal storage and microSD expansion up to 1TB. That combination is useful for lossless libraries, high-resolution downloads and long trips, although your usable capacity will be lower after the operating system and formatting.
The supplied material does not establish an equivalent NW-WM1ZM2 storage figure, so storage should be checked on the exact regional Sony listing before purchase. The same caution applies to battery life: the cited 10-hour figure belongs to What Hi-Fi?’s SP3000 entry, while no directly comparable Sony or separate SP3000T figure is established here. Battery endurance also varies with screen use, wireless functions, volume, file type and output mode; do not treat a single published number as a universal travel result.
Recommended Free Tools
For either player, plan your library around the actual files you carry. DSD and high-sample-rate PCM consume more space than CD-quality lossless albums. If you rely on a microSD card, use a reputable card, format it in the player’s supported file system and keep a second copy of irreplaceable music.

Price and value: why a sound winner is not automatically a value winner
Both products occupy the luxury DAP category. The supplied material does not provide current regional prices, promotions or verified availability, so it cannot support a universal value verdict. TechRadar explicitly notes that the SP3000’s price limits value, but that observation does not establish how it compares with the NW-WM1ZM2 in your country or at a particular sale price.
Evaluate the premium in terms of features you will actually use:
- Pay for the SP3000T’s output flexibility if you own headphones with 2.5mm or 4.4mm balanced cables, or if the published 6.3Vrms balanced output solves a real drive requirement.
- Pay for Sony’s design if its stated rich, full-bodied and spacious balance is the sound you repeatedly prefer and the chassis and S-Master HX implementation matter to you.
- Do not pay for format headroom you cannot use. Native DSD512 and 32-bit/768kHz support are useful only when your library and playback chain contain material at those rates.
- Include the cost of balanced cables, microSD storage, protective accessories and regional warranty support when comparing totals.
A practical audition method
Use a short, repeatable playlist rather than switching randomly between albums. Include an intimate vocal recording, a bass-heavy track, a dense orchestral or electronic passage, and a quiet acoustic recording. Use files from the same master when possible.
- Disable sound-altering effects and set both players to the same gain and output mode where the controls allow it.
- Use the same headphones, cable type and source files. If one player uses balanced output and the other uses single-ended, note that the comparison is also testing the output path and available headroom.
- Match volume before judging detail, bass or soundstage. Even a small level difference can bias the result.
- Listen for specific traits: vocal body and sibilance, bass start-and-stop control, separation during dense passages, treble fatigue and the stability of the stereo image.
- Repeat the test after a break. A player that sounds impressive for five minutes but tiring over an hour is a poor long-term match.
Which player should you buy?
Choose the Sony NW-WM1ZM2 when
- You prefer a rich, full-bodied and spacious presentation.
- Your headphones are lean, bright or light in the mid-bass and may benefit from additional body.
- You want Sony’s S-Master HX amplification, Native DSD support and documented balanced/high-power capability.
- The gold-plated oxygen-free-copper chassis and Sony’s stated low-noise design priorities are meaningful to you.
Choose the Astell&Kern SP3000T when
- You prefer the cohesive, balanced, authoritative and muscular presentation reported for the SP3000.
- You need a broad connector selection or plan to use balanced cables.
- Your headphones benefit from substantial voltage headroom and the 6.3Vrms balanced specification is appropriate for their load.
- You value PCM up to 32-bit/768kHz, Native DSD512 and a highly specified conversion architecture.
- The 256GB storage and up-to-1TB microSD expansion cited for the SP3000 fit your library plans.
Choose neither immediately when
- You have not identified your headphones’ impedance, sensitivity and cable requirements.
- You are expecting a luxury DAP to transform a poor recording or low-quality source file.
- You need a firm battery or storage comparison but have not checked the exact regional model listing, especially for the SP3000T and NW-WM1ZM2.
- You cannot audition at matched volume and with the same headphones.
Common mistakes to avoid
- Equating more DACs with better sound. Architecture is relevant, but implementation, output stage, recording quality and headphone matching determine what you hear.
- Assuming balanced always sounds better. Balanced output can add headroom and reduce the need for adapters, but it is not a universal tonal upgrade.
- Mixing model evidence. A review of the SP300 is not automatically a test of the SP300T. Keep the model names attached to every specification and listening description.
- Using manufacturer language as a measurement. Sony’s claims about noise, vocals, bass and space describe design intent; they are not controlled proof against Astell&Kern.
- Ignoring the recording. A well-mastered album at ordinary lossless resolution can be more satisfying than a poorly mastered ultra-high-resolution file.
The decisive question is not whether Sony or Astell&Kern wins in the abstract. It is whether your headphones and listening habits reward Sony’s richer, more spacious target or Astell&Kern’s balanced, authoritative approach, and whether you will use the SP3000 family’s extra outputs, voltage headroom and storage options.
