Still only 1.4V output on dac card?
Or is it 2V now?
I believe it's outputting the full 2v this time. I ordered the Asgard 3 with Delta-sigma dac module--when I receive it I'll put a meter on it and check the voltage.
The latest DAC module revision runs two 4490's in parallel going to a pair of op amps for a buffer, OPA1662. This should result in similar performance of modi 3 but I'm not completely sure.
The prior DAC module design had the same DC blocking capacitors as the modi 2 and no sign of a buffer which leads me to think they solved the problem. Here are some pictures:
