iFi Nano-iDSD PCM/DSD/DXD Battery Powered USB DAC Decoder #NANO IDSD

The iFi nano iDSD is full of 'firsts.' It is the world's smallest, portable (only 163g), battery-powered, serious DAC that plays ALL high-resolution formats: PCM/DSD/DXD natively. Its portable form belies its bleeding-edge technological design. With the latest breakthrough True Native technology from AMR, the music format remains unchanged throughout. PCM (32bit/384kHz), DSD256 (11.2MHz) and DXD (384kHz) via Computer or iPhone/iPad/Android simply sounds stunning; opening up a whole new world of high-end audio quality to a whole new generation of users.

In a palm-sized chassis with an onboard lithium-polymer battery and headphone output, the iDSD is as extraordinary 'on the go' as it is in a 'high-end system'. It handles Computers/Smartphones with aplomb. It even features an SPDIF coax digital output for A/V receivers or similar to offer unrivalled flexibility. The iDSD. Small in size. Tremendous in technology.

Having a chipset able to play all formats would count for little if this was not all executed natively; without conversion from one format to another. Using trickle-down technology from AMR (who drafted the chipset code) to drive this Burr-Brown chipset, the original music format remains unchanged which is essential to attaining the zenith in high-end audio reproduction. Computer-audio playback is advancing at breakneck speed. The iDSD is at the cutting-edge.

The focus on portable devices has positioned the iDSD at the forefront of this latest audio shift. Not only on computers, but the iDSD coupled with an iPhone/iPad/Android device, becomes a high-end audio source; able to play all formats, stunningly well:

PCM from 16/44kHz all the way up to 32/384kHz
Quad-Speed DSD to 11.2/12.4MHz
DXD up to 384kHz

Such a multi-talented DAC is seldom seen at any price which just goes to show the iDSD is state-of-the art, despite its affordable price. The latest advancements in Smart Devices such as iPhone/iPad/Android has transformed them from a mobile phone to a portable, high-end Computer Audio Source. These Smart Devices are able to natively encode and transmit high-res PCM/DSD/DXD audio. As the iDSD is able to natively decode the same, this high-end 'Transport+DAC' combination offers astounding sonics yet is all just palm-sized and able to be enjoyed on the move as well as at home. Each high-resolution format is beng replayed, even DSD on 5.6MHz (the iDSD actually plays all the way up to 6.2MHz!).

The iDSD features an onboard lithium-polymer battery. This offers two distinct advantages. First, sonically-speaking, the iDSD is able to run on battery power for excellent sonics over generic noisy mains. Second, the iDSD via its powerful 80mW headphone amplifier offers high-end, portable audio enjoyment. However, for ultimate sonics at home, it is also possible to run off the iUSB Power (via USB port) just by powering on the iDSD prior to connection to the PC. The iDSD offers the best of battery and iFi USB power.

There are clock crystals and there are the clock crystals in the iDSD. The 'clocks' used in the iDSD which have been supplied by AMR, are military-grade temperature compensated master clock modules which avoid the creation of unwanted beat frequencies. Such crystals reduce overall digital noise and push jitter to the vanishing point. These clocks have been specifically-sourced from the telecommunications industry where standards are far more exacting than those in the industrial sector (which normally supplies to the audio industry). Expect the iDSD to sonically compete with far more expensive DACs. Its smooth, 'analogue' sound is in large part, due to the overall quality of its components such as its special clocks.
