Small size – big features
This small desktop DAC is capable of high-resolution audio playback of up to 32-bit, 768 kHz PCM and DSD512! Pre Box S2 Digital also supports hardware MQA unfolding.
With organic polymer capacitors and thin-film miniMELF resistors, we were able to create a tiny device that will even blow away much larger components at a much higher price.
