Nice to meet you, Kean.
If you can't use the AKM DAC, then the ESS ES9038Pro*2 implementation would be suitable for you.
Also, although this is not common, I think you could implement CPLD processing before the ES9038Pro to achieve a lower level of distortion.
Thank you.

Yes, we will continue the K9 project with ES9038PRO*2,the functions and circuit will be changed also.
We maybe start K9Pro first

Unfortunately, BB AUDIO DAC chip does not support high sampling rates,such as 384k

Any idea on release dates? I'm really wanting an all in one and would like to get this.

800+ (K9 Pro) vs 200 (K5 Pro). Wide price range, so enough space for something in the middle.

Double Sabre Pro chip, my yeah! Must be a killer.
I wonder, as i use optical only, that his dac can upsample internally at least to 96khz, or maybe up to 24bit/192. I just don't see this usual feature, which in my opinion is necessary, basically anywhere :/

Upsampling is generally a silly feature though. Internally Sabre and AKM DAC oversample to MHz rates (from kHz). Doing a little upsampling before that won't really improve things (except perhaps jitter, which in modern DACs shouldn't ever be an issue anyway).
Upsampling was a big thing years ago with first USB DACs. Nowadays you rarely see it anymore because people know better...

Too bad they didn't stick with the look from the original post, because it would have looked 1000% better to me.

I guess you're talking about high-sample rate like DSD512 or 712KHZ? Which in optical without upsampling software i couldn't get, so i'm stuck at 44/48khz if i'm not mistaken? With recent dac like Topping E30
