From a purely technical perspective, highlights of the iDSD nano include:
· Use of a “Native DSD/DXD/PCM BurrBrown DAC chipset,
· Support for all of the formats listed above via “High Definition USB Audio”,
· Support for Asynchronous USB and what iFi terms “Bit-Perfect” file transfers,
· Use of iFi’s proprietary ZeroJitter Lite technology,
· Outputs: A coaxial S/PDIF digital audio output, plus two stereo analogue audio outputs via a pair of RCA jacks and the 3.5mm stereo mini-jack,
· Controls: A rotary on/off switch and volume control, plus a mini-toggle switch for selecting either “Standard” or “Minimum Phase” digital filer settings, and
· A built-in headphone amplifier that features iFi’s DirectDrive technology and that offers claimed power output of 130mW.
The iDSD nano requires no additional device drivers for use in MacOSX environments, but for use in Windows environments it is necessary to download and install a free device driver from the iFi web site.
