The new nano iDSD Black Label has a maximum output power that is around 10 times of the iPhone, which allows the nano iDSD Black Label to drive most headphones in the market. Like the nano iDSD, the nano iDSD BL is small, lightweight and battery powered for ease of portability. The Lithium Polymer battery gives the device 10 hours of continuous use. One of the main feature of the nano iDSD BL is its support on the MQA format that brings hi-res audio streaming into reality. The device is also capable of supporting PCM up to 32 / 384 kHz and up to DSD 256. The device gives the user filter options like Listen (Minimum Phase Bezier Filter) and Measure (Linear Phase Transient Aligned Filter) to give more control on preference. Finally, the nano iDSD BL has built-in IEMatch circuit to ensure that even the most sensitive headphones or IEM are hiss free through out the volume range and also includes S-Balanced wiring to give the benefit of balanced outputs when used with headphones and IEMs fitted with balanced wiring.3
