We just received this from our Portugal distributor and just had to share!
Translation from the image: The iDSD is a converter for streaming and also integrates an amplifier for headphones. What iFIs Audio managed to put in a box so small? Well, nothing less than a lithium battery with a capacity of 10 hours of operation, depending on used headphone and volume, of course, and integrating the latest chips developed by Burr Brown in Japan. The chip is the DSD1793 and, as the name implies, supports DSD format as PCM, with a resolution of up to 24 bit, having a 113 dB dynamic range and a maximum distortion of 0.001%. The iDSD uses Zero Jitter Lite technology from AMR and have also an integrated circuit specific for headphone signals amplification.
In terms of input, digital formats the Nano iDSD accepts PCM from 16 bit/44 .1 kHz to 32 bit/384 kHz, DSD bit until 6.2 MHz and DXD until 384 kHz.
