We've added yet another file format to our portfolio in the form of MQA in the new BL. Take TIDAL or your MQA file to a whole new level. MQA is an audio technology developed by Bob Stuart. This technology makes hi-res audio streaming a reality and delivers studio master quality audio to your headphones.For mobile DACs with both portability and power considerations, MQA Rendering is the ideal solution as the workload is shared between the host (computer) and the client (DAC). In this case, for a DAC such as the nano iDSD BL, less CPU processing and lower electrical power are needed. This approach for the iFi portable range remains a full end-to-end MQA solution and the listener still enjoys the full benefits of MQA without compromise.High-Res Audio CertifiedThe nano iDSD Black Label is one of the best native highest-resolution DACs you can find, supporting PCM up to 32/384 kHz and DSD up to 256 times the sample rate of a CD, even on Mac OSX and mobile phones.
