The firmware for all built in USB32 as USB interface DAC, but not for the DI-V3 because it is limit 24bit on SPDIF transmit. We have declare on the web :  The firmware only for the DACs not for the DI V3.   The DI V3 firmware have finished at the same time of the DACs firmware but we like to test with DACs users at first. The DI-V3 firmware will release later if the test have not matter.
Up to 384K support with foobar and Jriver under Win7 64bit.

Around 10% can't appled because the terrible click noise.   In some case of our test, turn the steps swich volume port slowly may have less click noise. If the noise a bit louder...
