[QUOTE="gavinbirss, post: 941023, member: 60"] One needs to be mindful of differentiating between hardware and software solutions. A typical DSD capable USB to i2s chipset when DSD is enabled will output the 2nd DSD channel (in the case of stereo) on the one of the output pins used for I2s. Knowing this a USB to I2S chipset with low pass filtering can be made a DSD "DAC". Add some output transformers and up the low output signal. Up-sampling in software will need CPU (for real-time playback), yes and there may even be some commercial solutions secretly using HQPlayer. [/QUOTE]
