Further clarification from Matrix.
The new driver added support of DSD256 and 32 bit for 2014 Mini-i Pro. At the same time, it may not display properly but it can be played normally. I'm so sorry that we will not release the new firmware update at present, and the 2014 Mini-i Pro could support the DSD256. Of course, the 32 bit enbale (I think she typed enable) to playback.
Version 2014 and 2015 digital volume control method is the same, the digital volume control is a internal function of ES9016, we just use this function to achieve digital volume control, but whether it is conversion DSD/PCM internally to allow digital volume, I think you need to consult ESS company.
Best regards,

Despite the incorrect display info, 2014 version works like 2015 version, old owner should be happy now. Regarding digital volume, it is available in both ES9018 / ES9016 as built-in feature, so Matrix (or any other brand) can decide to use or not to use, like its X-sabre has no physical volume control, Mini-i Pro can bypass volume control by entering pre-amp mode so it is volumeless like X-Sabre. So..... if there is internal volume control feature (with or without physical volume control), can we conclude that ES9018/9016 doing DSD/PCM conversion internally?
Almost all brands adopting ESS chip denied there is DSD/PCM conversion process. Yes, only ESS knows.
