FutureShop is an authorised dealer for Astell&Kern, a South Korean digital audio brand founded in 2012 by iriver, whose Digital Audio Players are used by recording professionals and audiophiles worldwide. This guide draws on direct in-store listening experience with the Astell&Kern range.
Our Verdict
For most first-time Astell&Kern buyers, the SR35 is the correct starting point: compact, genuinely long battery life, and a quad-DAC implementation that outperforms anything a smartphone can achieve. For those who need desktop-class output power in a portable format, the KANN Ultra is the definitive recommendation. For the most demanding portable listening with analogue amp-mode switching, the SP3000T and SP3000M represent the current state of the art from Astell&Kern.
Quick Take
- All four 2025 Astell&Kern DAPs include balanced 4.4mm output alongside 3.5mm and 2.5mm, support native DSD playback, and run Android allowing direct installation of streaming apps including TIDAL, Qobuz, and Spotify.
- The SR35 uses quad Cirrus Logic CS43198 DACs for a 20-hour battery life and is Roon Ready. It also operates as a USB DAC when connected to a computer or phone, making it the most versatile everyday carry.
- The KANN Ultra adds triple output modes (headphone, line-out, pre-out) and the Digital Audio Remaster (DAR) upsampling engine, making it suitable as a desktop source component as well as a portable.
- The SP3000T's switchable Triple Amp System (Class A, Tube, Hybrid) is unique in the A&K range and allows the character of the output to be changed without leaving the player's menu.
- The SP3000M is A&K's most compact flagship, using a separate HEXA circuit to isolate digital and analogue sections with a silver-plated shield, achieving a native SNR of 130dB.
Known for their uncompromising sound quality, premium materials, and innovative digital audio technology, Astell&Kern remains the gold standard in high-resolution portable music players. Whether you're a long-time audiophile or just beginning to explore lossless listening, Astell&Kern offers a range of Digital Audio Players (DAPs) to suit every need. In this 2025 buyer's guide, we break down the current A&K lineup and help you decide which model best fits your listening style and budget.

Matching Your Headphones to the Right A&K Player
The choice of DAP is inseparable from the choice of headphones. The output impedance and power capability of each model determines how well it will drive different headphone types. Choosing a player mismatched to your headphones is the most common cause of underwhelming results from an otherwise excellent DAP.
In-ear monitors (IEMs): IEMs are typically high-sensitivity and low-impedance, meaning they reveal background noise more readily than full-size headphones. For IEM listeners, output noise floor is the most critical specification. The SR35's quad Cirrus Logic implementation delivers a very low noise floor at its 3.5mm output and is well matched to sensitive IEMs. The SP3000M and SP3000T are also excellent, with the HEXA circuit and silver-plated chassis specifically designed to minimise ground noise. If you use high-sensitivity custom IEMs with impedances below 20 ohms, exercise caution with the KANN Ultra's high-gain mode as even its low-gain setting may produce audible hiss with the most sensitive IEMs.
Full-size dynamic driver headphones (32 to 150 ohm): All four A&K players handle this category comfortably. The SR35 is adequate for most headphones in this range through its 4.4mm balanced output. The KANN Ultra's high output power makes it the strongest choice for headphones at the higher end of this impedance range (100 to 150 ohm), such as the Sennheiser HD 650 or Beyerdynamic DT 990 Pro, where additional current delivery improves bass control and dynamic headroom.
Planar magnetic headphones: Planar magnetic headphones, including models from Audeze, are typically low-impedance but low-sensitivity, requiring significantly more current than the impedance figure suggests. The KANN Ultra is the strongest recommendation in the A&K range for planar magnetic listeners: its high output power per channel gives it the current delivery to control planars properly. The SP3000M can also drive planars well from its balanced 4.4mm output, though listeners with very demanding planars such as the Audeze LCD-X or LCD-5 will find the KANN Ultra's headroom more comfortable. Our guide to planar magnetic vs dynamic driver headphone technology covers why planars have different drive requirements in more detail.
High-impedance headphones (200 to 600 ohm): A&K DAPs are optimised for portable use and are not the ideal amplifier for 300 or 600 ohm headphones such as the Sennheiser HD 800S or Beyerdynamic T1. The KANN Ultra comes closest to adequate current delivery for these loads from its balanced 4.4mm output, but a dedicated headphone amplifier remains preferable for extended listening with very high impedance headphones.

How to Choose the Right Astell&Kern Player
| User Type | Recommended Model | Why? |
|---|---|---|
| First-time audiophile | A&norma SR35 | Affordable, compact, excellent sound for the price |
| Desktop audiophile with streaming | Kann Max | High power output and native streaming app support |
| High-end collector or purist | A&ultima SP3000M | Flagship-grade hardware and unmatched audio fidelity |
When selecting the right model, consider the following:
- Use case: Are you using it on the go or as part of a desktop setup?
- Output needs: Will you use IEMs or full-sized headphones?
- Audio format preference: Do you need native DSD, MQA support, or streaming capabilities?
- Portability vs power: Lighter models are more travel-friendly, but may have lower output power.
- Budget: Astell&Kern offers options from ~£600 up to £3,000+.
A&K's tiered lineup means there is a product for every listener, from entry-level explorers to seasoned purists.
Portable Alternatives: HC3, HC4 and HB1
