Then I stand corrected, although the article does conflate DSD decoding with The "remastering engine". Just cause it can decode it doesn't mean it can resample PCM into DSD. Those are 2 seperate features.

I swear by their WH1000s and WF1000s

Its a good thing lots of people do, cause they make my Xperia purchases $250 cheaper. The freebie buds go right to eBay.

This feature ensures the NW-ZX707 can transform standard MP3 or PCM audio to the ultra-high frequency 11.2 Mhz DSD audio stream.

I think the article is just incorrect. Sony probably means it can just decide .dsf files. And you are confusing 1 bit DSD with 16 bit PCM. The most common DSD format is DSD64 2.8Mhz which is equivalent to 16 bit /176khz, 24 bit/117khz, or 32 bit/ 88.2khz. And the microphones and instruments do work at these high frequencies.

There's Thunder (slick UI), Liftoff (best if you have multiple accounts), and connect (customizable). They are all pretty different so I'd just look at each of them and see what works for you.
