Well, if you'd be happy with 7.1 48 kHz digital audio you can do what I did: take the "audio" HDMI PCM feed from a 4k bluray player into an SDI02 to get SDI, then an AES/EBU SDI deembedder (Blackmagic, or better AJA), a minidsp DDRC-88D for bass management and Dirac Live (and digital volume control if you accept the resolution loss from 24 bit audio) into your DAC of choice. I use an old Lucid 8824 (85dB SINAD) (and two minidsp nanoAVRs instead of one DDRC-88D) but could have just as well used an Okto DAC8 for 118 dB SINAD (and analog volume control -- it's on my list).
Downsides? 48 kHz. Period. And no immersive formats: 7.1 is as best as you can get.
I've been looking for Atmos processors as good and am considering the Audio control X9 and JBL Synthesis SDP-55 (Dante, yay!) but problems with the latter and a lack if reviews of either leave me hanging. I've thought of a Rube Goldberg contraption with a $4k processor just for the Atmos channels but that would require coordination of levels, delays, and decoding of the base Dolby or DTS 7.1 tracks. The X9 at $9600 starts to look cheap (with claimed 100 dB SINAD figures). But: no reviews.
