Is there some way to correct for the errors? One part in 10,000 is going to give a little more than 13 bit accuracy.

You can laser trim the chip as in the case of Krell with the PCM63

No, hence 0.1% when the price is reasonable.
There is actually another variable; 0.01% resistors of what kind. Vishays will be best but the cost!!!!!!! And you can have better than 0.01% with 1ppm tempco.
