Dear Kingwa,
I seen in specs for device NFB-29 support dsd64/dsd128 format.
But, i could not to reproduce dsd128 on my DAC.
I use latest drivers and firmware from your official site http://www.audio-gd.com/Pro/dac/USB32/USB32EN.htm.
I use Windows7, and hight quality USB-cable.
Also i tries to use many variants of settings in OS and ASIO drivers, according to your instructions, but result is negative!
