Any 32bit Delta Sigma/ R-2R Audio DAC in the world?

Can be chips or module.
I want some details about this.
Thanks~!

Does not exist and will not exist as such a beasty is physically
nonsense. Pray do the exercise: take a 2V full scale level, calculate
the equivalent voltage for the LSB, and compare this to the thermal
noise at room temperature of, oh, a 10 Ohms resistor ...

Additionally, the motivation to use delta-sigma converters is the possibility to achieve high signal resolution by the use of low-resolution/fast-sampling converters.

32 bit is heavy but I suggest that we concetrate us to make a true 24 bit converter! Right now we have 21.5 bits, right?
