Hi I'm having trouble hunting down a 16-bit DAC chip that uses an R2R network for conversion.
Even better would be a DIY kit for a computer DAC using such a chip.
Does such a thing exist?

Hi, Sorry all current production audio dacs are sigma delta or bitstream,even
for PC usb use.I think you still can get TDA 1541A,PCM63,PCM1702 or even the more recent PCM1704 24bit.There are chinese boards if you do a search.

Do you literally want an R2R based DAC or do you mean a 'old fashioned' binary weighted DAC as opposed to a sigma-delta based DAC? The monolithic IC parts so far mentioned aren't actually R2R as that approach has limited usefulness in practice owing to infinitesmal output compliance.
I did inquire them about one of their products and they replied "thanks for interest".
From a company that has it's HC in a suite on second floor of a building that has bars at the first floor, I would take their claims with a grain of salt.

An externally hosted image should be here but it was not working when we last tested it.
I suppose not. My background is in instrumentation - bad things happen if not Monotonic 😱
Many consider the PCM56 to be one of the best 16-bit DAC chips. In addition to the PCM56 there is the 100% compatible AD1856 from Analog Devices. Both chips are currently in production.
AKM 4396?
I' m not sure about this one, but I read somewhere that the AKM 4396 and later 4399 DACs are similar to the "ring dac" concept and uses R2R.
If this is the case, an inexpensive and fun way to play with that would be to start with a Behringer DEQ 2496, take out the AKM 4393 that is in there and drop in the '96. Then you can take the outputs of the '96 directly into a 1:1 transformer, or coupling caps on both signal legs (A+ and A- on the AKM pinouts) or whatever buffer amp you choose.
I've done the direct out with the 4393, sounds great. Other members (Sendler is one of them), have done the 93 to 96 conversion and report fantastic results.
In essence, you could simply use the Behringer as your DAC... just make sure you go digital input and direct DAC out, making sure you bypass the Behringer's analog circuitry which is not particularly good sounding. Also, when going DAC direct out, it is less important to mod the PS on the Behringer because you are only using the 6V and 3.3V sections which are fairly decent.
So's if it's R2R, that might be a good thing for you to check out.
