Guys, this DAC is 18-bit ladder, not a true 24-bit found in Holo Springs. It doesn't have linearity compensation built-in, it requires two identical sets to this job! Moreover, it can't bypass the hardware OS, so basically it cannot do NOS. In Denafrips TW website specs can do up to DSD128 (6.114MHz), not DSD256 (11.28MHz) and not even DSD512(22.5MHz) that Holo Spring can do! Moreover the Windows USB driver is generic XMOS driver not designed by Denafrips and it can't do DSD in native mode, only in DoP. Holo Spring Windows driver are designed by Holo Springs through a third party driver manufacturer Thresycon and Microsoft signed driver that does DSD in native mode all the way to DSD512!
