Colorfly Pocket Hi-Fi C4
The audiophiles' PMP
Review The true audiophile is likely to have many questions concerning the Colorfly Pocket Hi-Fi, but chief among them is likely to be ‘How f*%&ing much??!?’ At £549 this Chinese-made high fidelity portable music player is nobody’s idea of a bargain, but if you’re one of those brave souls who still cares about sound quality, who appreciates the convenience of digital but feels cheated by the compressed sound, Colorfly might just have something here.
Listening skills: Colorfly's Pocket Hi-Fi C4
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, but on USB cable this seems like overkill.
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.
Metering on-screen: ah, takes you back
Admittedly, you might need the hearing of a dog to notice improvements in high frequency decoding the Colorfly has the potential to deliver. Likewise, the Colorfly makes great play out of the C4's jitter performance – minimising timing errors that have an impact on vocal reproduction.
Taking the Flac
Uncompressed hi-res audio files take up a lot space, but thankfully there’s 32GB of storage on-board, and you can boost it by a further 32GB using the micro SD slot. Next to the 3.5mm minijack, the full-size 1/4in stereo headphone jack is another audiophile crowdpleaser.
Format support could do with expanding, but firmware updates are appearing that add functionality
In tests, 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. There is a downside though: the battery life, during my random usage, never made it into double figures.
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.
Digital interfacing broadens its versatility beyond a portable music player
If you spend any time at all on the Colorfly web site, you'll be convinced that the brains behind this portable player belong to audiophiles. Every aspect of the audio signal chain appears to have been scrutinised in order to deliver a quality product that’s versatile and genuinely capable bit of kit. Rarer still, in the portable world, is that it qualifies as a high-end component too.
At this price – and given its frankly, over-engineered design – the Colorfly is always going to be a niche product. But if you care about the subtle nuances of sound reproduction, and can appreciate the difference between an MP3 and a FLAC file, then it’s definitely worth a look... and a listen. ®
