FiiO Snowsky ECHO NANO Purple Edition – Compact Hi-res Audio Player with CS43131 DAC in a New Colour

Compact digital audio players have long since ceased to require the appearance of miniature smartphones. Guangzhou FiiO Electronics Technology Co. Ltd. pursues precisely this idea through its Snowsky brand and the FiiO Snowsky ECHO NANO. The tiny player borrows the clear, functional aesthetic of classic MP3 players, yet combines it with an aluminium-magnesium enclosure, a dedicated D/A converter and support for Hi-res Audio formats. The new FiiO Snowsky ECHO NANO Purple Edition leaves the technical platform unchanged, but gives the player – weighing only 33.5 g – a considerably more individual identity through its vivid purple finish.

Purple Edition Adds a Distinctive New Accent

The Purple Edition makes no changes to the fundamental design of the FiiO Snowsky ECHO NANO. Its slender enclosure measures only 81 × 20 × 11 mm and is manufactured from a 6000-series aluminium-magnesium alloy. CNC machining is used to provide precisely defined edges and a suitably clean surface finish.

With the purple version, Snowsky places greater emphasis on the player’s fashionable character than it did with the previous finishes. The ECHO NANO is therefore positioned not merely as an especially affordable playback device, but also as a deliberately styled personal accessory.

Its nostalgic inspiration is unmistakable, yet the materials and manufacturing are intended to meet the expectations associated with a contemporary personal-audio product.

A Multifunction Control Wheel Instead of a Touchscreen

One of the player’s defining design features is the recessed metal control wheel on its upper edge. It handles volume adjustment, power and activation or deactivation of the display, allowing most basic operations to be performed comfortably with one hand.

A 0.91-inch OLED screen displays track information and the current operating status. The interface is intentionally reduced to the essentials and will particularly appeal to listeners who want to enjoy music on the move without the apps, notifications and other distractions of a smartphone.

Compatible earphones and headsets with CTIA-standard in-line controls are also supported. Depending on the connected model, playback, track selection and volume can consequently be controlled directly from the cable.

Cirrus Logic CS43131 DAC and Native DSD256 Playback

Digital-to-analogue conversion is entrusted to a Cirrus Logic CS43131 DAC. Snowsky combines it with a separate crystal oscillator designed specifically for audio applications.

The player supports PCM material in WAV, FLAC and APE at resolutions of up to 24 Bit and 192 kHz. DSD files can be reproduced natively at up to DSD256. MP3, M4A and OGG are supported as well, with microSD cards of up to 256 GByte serving as local storage.

A 3,5 mm stereo mini-jack is provided for wired headphones and earphones. According to the manufacturer, the output stage delivers 120 mW per channel into 32 Ohms at a total harmonic distortion of less than one per cent. The quoted signal-to-noise ratio is at least 127 dB, while noise is specified at 0.7 µV.

That should prove sufficient for readily driven in-ear monitors and many compact portable headphones. Demanding full-size headphones are clearly not the primary application here, but the available power is respectable given the ECHO NANO’s size and price.

USB DAC Operation for Smartphones and Computers

The FiiO Snowsky ECHO NANO Purple Edition is not restricted to use as a standalone player. Connected via USB to a smartphone, tablet or computer, it can operate as an external audio interface using USB Audio Class.

In USB DAC mode, it processes PCM signals at up to 16 Bit and 48 kHz. Charging can be disabled during operation, preventing the ECHO NANO from drawing additional power from a connected smartphone.

The USB implementation does not offer the same maximum resolution as standalone playback, but it nevertheless adds considerable practical value to such an inexpensive device. The ECHO NANO can therefore serve both as a self-contained pocket player and as a compact external DAC for everyday mobile or desktop use.

Conclusion

The FiiO Snowsky ECHO NANO Purple Edition introduces no new technology, merely a new colour – but that is entirely relevant in this particular case. After all, the tiny player draws as much of its appeal from its retro character as it does from its Cirrus Logic CS43131 DAC and support for Hi-res Audio formats.

The bold purple finish adds a playful sense of individuality that suits the deliberately pared-back operating concept particularly well. At € 54.90, Guangzhou FiiO Electronics Technology Co. Ltd. also provides a surprising amount of substance: a metal enclosure, expandable microSD storage, native DSD256 playback, useful output power and even the ability to operate as a USB DAC.
