Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
What's your approach to customer support?
Musical Fidelity (like other Audio Tuning brands) is structured in a pretty traditional way, whereby support and advice are best administered on a local level. Of course, they have a technical team positioned at HQ to help all their partners around the world, and in some more extreme cases you may need to be put straight through to this team. But it's the job of the distributor to support the territory in the best way it can.
What are your favorite tracks for showcasing the strength of your products?
I can tell you this, as we've done this recently for others. These are personal choices:
Simon Quarry – the chief designer – selected these three.
- Low Desert Punk – Brant Bjork
- Moon Love – Electric Moon
- Psychic Chasm – Ozric Tentacles
Heinz Lichtenegger – the brand owner – selected these two:
- Tosca – Puccini, Leontyne Price, Di Stefano, Taddei / Vienna Philharmonic with Herbert von Karajan (Decca, 1963)
- Don Juan – Richard Strauss, Tod und Verklaerung, Also Sprach Zarathustra / Vienna Philharmonic with Herbert von Karajan (Decca, 1960)
What other products pair best with yours?
This is a tough one! Partly because of the diverse range of products on offer from Musical Fidelity. For example, with the A1, we have a lot of success pairing this amp with Klipsch Heresy or Forte IV – but in smaller rooms, our own-brand LS3/5A are a wonderful choice. For Nu-Vista, we pair very nicely with Piega – which requires some deeper power reserves to really get going. So I would say it's very difficult to pair the sonic ID with one brand in particular. Musical Fidelity pairs pretty nicely with a wide range of products, giving customers a great degree of choice.

Product Strengths
- Fully balanced technology, with balanced inputs and outputs.
- Delivers powerful amplification, with up to 7.5 watts of power, capable of driving a wide range of headphones, including hard-to-drive models.
- Features a linear power supply with a large transformer and capacitor bank, providing a stable and powerful power source.
- Provides two current modes (50mA and 100mA) to tailor the sound tonality, allowing users to choose between a more forward/analytical sound and a warmer/fuller sound.
- Employs an R2R network for volume control, ensuring channel balance even at low volumes.
Product Considerations
- Runs quite hot due to its Class A amplification, requiring adequate ventilation, with chassis temperatures potentially reaching up to 50 degrees Celsius, and the unit may switch from 100mA to 50mA mode if it overheats.
- High power output might not be ideal for very sensitive IEMs, potentially limiting volume control flexibility.
- The preamplifier output is always active, meaning it doesn't mute when headphones are plugged in, requiring caution to prevent damage.
- The LCD display cannot be dimmed or switched off, and the red color of the 100mA mode may appear washed out.
- Some report volume slots are not regular or have large jumps, and/or that the remote control can be buggy.
Comparisons (according to reviewers)
- Vs. Topping A90 Discrete: The S17 has a richer sound, wider soundstage, and easier dynamics, especially in 100mA mode, placing it in a higher tier.
- Vs. Topping A90D: The S17 Pro is capable of even stronger dynamic swings, with a slightly cleaner and less cluttered soundstage.
- Vs. Violectric V222: The Aune S17 Pro is more 'tubey' and warmer sounding than the V222.
- Vs. HIFIMAN EF600: The Aune S17 has better volume control, higher dynamic range, better driving power, and better resolution.
Takeaway: The Aune S17 Pro is a powerful and versatile headphone amplifier that delivers rich, detailed sound, allowing listeners to experience music in new ways. With its balanced design and flexible current modes, it can enhance a wide range of headphones and audio setups.
