Discrete  DAC+ Head amp / Preamp / Line In
32bit / 384K Asynchronous Transfer  USB-32 Chip 
32bit / 384K dual DA chips
Suggest : New Hifiers if confuse for the modules choice, we advice purchase the default version, after several hundreds hours burn in and evaluate which side want to improve for the best personal taste , then contact us for  the modules choice and purchase .
