AKM makes the best DACs

To be clear, I was specifically asking about ...

For converters which use an all in one chip ...

Perhaps someone should start a separate thread for DACs which use only in house electronics for the converter.

I love my Bryston DAC, which uses an AKM chip, but didn't the AKM factory burn down about a year ago?

That sounds like redesign work for audio manufacturers who have been using the previous generation of chips.

Probably not for all of them. DAC's aren't like PC CPUs which constantly need new sockets for new features.  The input streams, power supplies, and outputs are fairly consistent.  AKM would be doing itself a favor by making at least some of their  updated chips with identical footprints. 

Still, given the advances in putting more CPU/DSP capabilities on a chip I'd expect them to release some with enhance the feature set, and therefore control codes.

In non FPGA DACs, I've tended to find that AKM chips sound the most natural, but most of the AKM based DACs I've listened to tend to be more expensive than those which use ESS and Burr Brown chips so the issue of anciallary components complicates things. FPGA-based DACs are a whole other category of course.

I haven't heard or owned a lot of DAC's, but have owned California Audio, Cambridge, Theta Digital, Schiit Yggy, and Cary.  Of those, the Cary DMS-700 was by far my favorite.  It uses the AKM AK4499EQ in conjunction with a FPGA chip and find it to be very analog sounding.  I have no inclination to change for a long time.
