Tbg,
I still say the inexpensive BMC PureDac is the best.
Though it is clear that the BMC is another Chinese-made product judging by the way it is built internally, I would agree with you that it packs unique technologies, unlike some "name brands". And I respect that.
I've met Clement Perry and Key Kim at the Munich show this year and promised them a DSD-S review sample. I am not sure when this will happen, but it will for sure. Promise is a promise.
So maybe you can get to listen to it as well, and let us know how you feel about it.
Best,
