Complete and intuitive audio control
ASUS Xonar U7 MKII comes with Sonic Studio, a full-featured and easy-to-use sound utility that gives users complete control over a wide range of audio features, such as equalization (EQ) and 7.1 surround speaker level-balancing.

Sonic Studio is fully compatible with Windows 10.

I will enlighten you that the slow driver releases are due to CMEDIA slowly releasing drivers.
ASUS does not make the drivers for the DAC, CMEDIA does.

Yes, and I know why ppl like how cmedia audio sounds like, its very realistic and soft and pure but cmedia really needs to rework stability and power output to make it last. Only then I will compare it to rough Sound Blasters that actually work.

I have a D2X for almost seven years (I think) now. It's working flawlessly. The question about this card is if it's compatible with Window's new usb audio core, which would mean that it could work with no drivers. If that's on, then it looks like a very nice product.

sorry man but it is not about the driver I think, those c-media chips look like made very very cheaply, like 5 dollar cheap, I did have 2 of Xonars, DGX and DX (both with problems) and many many years earlier this:
In a sound card that costs 10 dollars total 10 years ago it was OK and many features in the drivers made it fantastic to use, but in a expensive Xonar ? big NO, audio output in DX gets weak in a month and stability issues appear like 1 channel with no output or 1 channel with just noise or both channels with no output or just cracklings while swapping music, DGX had no power at the begging to power even 50 ohm headphones and equalising the lack of punch made all of the output to jump over all of the frequency range.
