Colourfly is a top-flight portable player or even an extension of your hifi system. Look at all the ways you can use it!

•    Plug in your favourite headphones and use the Colorfly as a high-end portable music source.

•    Use it as an analogue music source and connect the analogue 6.5mm output directly to your hifi system. (Use an optional adapter cable - stereo 6.5mm to RCA)

•    As an SP/DIF digital source of music without mechanical vibration caused by moving parts and with a battery power supply.

•    Acting as a DAC (digital to analogue converter) using the SP/DIF digital input and analog output and up-sampling is also possible.

The Colorfly C4 can be used as a hifi sample rate converter, using the coaxial digital input and then the coaxial digital output. Jitter can be reduced!

Why does it sound so good? The excellent 24 bit / 192kHz (maximum) sound quality is largely due to the single hifi DAC (Digital-to-Analogue Converter) that has been used inside the Pocket Hifi C4. The team who designed the Colorfly Pocket hifi C4 Pro used the CIRRUS logic CS4398, a high-end chipset usually only found in top-of the-range hifi components. This DAC offers outstanding levels of performance with excellent dynamic range up to 120dB and the ability to decode up to 24bit / 192kHz (WAV) audio depending on the format.

·Pocket HiFi C4 shell wood produced from the North American black walnut, they are the best once the title of Royal walnut. This wood texture is not only thorough, smooth and delicate, glossy, ring clear, and sometimes with wavy or curly tree pattern to form a pleasing decorative patterns. Due to the unique wood grain, each player is unique.

Colorfly used the flagship series pro-audio series of the famous ALPS volume potentiometer in Japan.

The dust cover and grounding connection were ordered according to the specifications of the Pocket HIFI player.

The rate of the volume error was lower than 5% in average after 1,000 hours. The volume error rates of the C4 was 15% lower than the ALPS official data.

The excellent sound quality and support for 24bit/ 192kHz is possible thanks to a single Hi-Fi DAC (Digital-to-Analogue Converter).

The ColorFly team decided to use the CIRRUS logic CS4398, a high-end chipset usually only found in top-of-the-range Hi-Fi components costing many thousands of pounds.

This DAC offers outstanding levels of performance with excellent dynamic range up to 120dB and the ability to decode 24bit/192kHz audio for stunning sound quality.

Everything about the Colorfly is designed to give the impression of quality, from the black walnut wood shell with engraved back to the supplied gold-plated USB/mini USB cable. At least some of this is pure affectation – gold-plated connections may be popular on hi-fi gear, apparently delivering a more robust connection.

The old-school aesthetics of the volume slider and big, chunky buttons won't appeal to everyone, but it feels very solidly built and combined with the interface – that includes metering of your audio levels – gives the air of reliability and class.

Virtually all digital music players these days make claims for 'great sound quality' but few take it to the extremes of the Colorfly Pocket Hi-Fi. It claims to be the only portable player capable of handling 24bit/192kHz audio files. By comparison, CD audio is 16-bit/44.1kHz and you could argue that there's no real need for such a high resolution, but music production kit is capable of producing recordings at this level, and so here’s a portable player to match.

Among the controls, the music note button lets you scroll through the half-dozen equaliser settings. The SRC button has upsampling options which will help clocking with other high-end digital gear – the Colorfly does feature coax S/PDIF I/O, after all – and any noticeable audible benefits of effectively oversampling will be in the ear of the beholder.

the Colorfly could handle 24-bit/192kHz Wav files, 16-bit/44.1kHz Flac, Ape and MP3 files. A new downloadable update will apparently allow it to play 24/192 Flac files too, though there’s no word yet on when or even if it will be able to play iTunes-friendly AAC files, or perhaps more appropriately, Apple Lossless or WMA Lossless formats.

Sure enough, the sound of the Colorfly is something of a revelation. Playing some 16-bit Flac files downloaded from posh speaker manufacturer Bower & Wilkins’ Society of Sound site was simply glorious. A Retrospective by North eastern folkies The Unthanks sounded deliciously close and personal – almost indecently intimate – sustaining the atmosphere with every tic and trace from the recording sessions evident.

While I struggled to notice any difference with the upsampled 192kHz playback of MP3 files compared to their 44.1kHz source resolution, the Colorfly undoubtedly delivers a fuller and more complete sound than the same tracks played on cheaper PMPs. Also, it delivers a terrific output volume that's more than most ears will be comfortable with at full blast.

Still, it’s not just a portable player, oh no. The high-end Cirrus Logic CS4398 DAC chip and the coaxial S/PDIF digital in and outputs mean it can also be employed as an upscaling DAC (Digital Analogue Converter) as part of a hi-fi or home cinema system, raising the bar on quality at home, as well as on the move
