NuPrime Hi-mDAC

FAIRLY NEW IN the UK, NuPrime's Hi-mDAC is the smallest and simplest converter it makes. Its decoding architecture is centred around a Cirrus Logic CS43131 DAC. Given that it lists similar (identical) adjustable filter options and the same 384kHz PCM and DSD256 handling as iFi's GO bar (p109), we can postulate that it's the same chip

Here it is partnered with a customised USB interface of unspecified origin. Unlike the iFi, it is exclusively single ended with a 3.5mm stereo output. As well as providing an analogue out, this can be switched to function as a USB-to-SP/Dif converter where the 3.5mm output transmits optical at sample rates up to 24-bit/192kHz.
