Yet another Discrete R2R Multibit Dac, this one from Audio GD.

Their all starting to jump in to do discrete r2r multibit.

how does the FPGA control and correct the R2R ladder?
I think Halo or someone does something similar, some sort of feedback correction to get accurate resistor tolerances. Just noticed it has a TCXO (temperature controlled) clock as well, with (PCM / DXD / DSD Native support.   

Being done by Audio GD it could be one to look out for for doing RedBook pcm, certainly priced right at $2.5k. Shipping prices from these guys are always cheap.

Here is a well done video preview by and independent reviewer, explaining in good detail how they get around R2R resistor accuracy.

Audio-gd has been doing R2R dacs for a long time
I have there Master 7 and it is a great dac
