The Micro iDSD Signature is capable of supporting PCM streams up to 768kHz, DSD streams up to 512, 2xDXD streams and even MQA files.
The DAC chips used are "True Native" Burr-Browns selected by iFi for their ability to natively manage all these encoding technologies (no conversion from one encoding to another before conversion into an analog signal), in order to maintain maximum audio quality from one format to another.
A status LED cleverly indicates the currently playing file format as well as its resolution to confirm at a glance that the audio playback and the conversion are taking place in the best conditions.
The circuit embeds the whole iFi signal correction arsenal. Particular care has been taken to reduce jitter thanks to a dynamic buffer memory and extensive use of femto clocks. The PCM / DSD and DXD filters are directly interchangeable via a three-position selector located on the side of the device.
