A Vout DAC chip like the ES9023 or PCM5102A is going to have noise floor modulation due to the embedded charge pump, limiting its performance.
TI recently released the PCM5242, which is a PCM5102 with embedded ROM/DSP, as well as differential voltage output, rather than single pole output. This makes it similar to the Wolfson chips, except with the added benefit of a line driver. Differential output will help with cancelling out some of the output noise, which makes the performance ceiling of this chip package higher, while remaining pretty affordable. A designer still needs not design an I/V converter (lowering complexity and BOM cost), and can directly hook up a differential input IC for the headamp, further simplifying BOM cost.
The embedded ROM allows for custom design of digital filters and oversampling routines, and can be selectively flashed for performance changes, like an FPGA, except with a less computational power.
A platform like this would end up more flexible than the ES9023 used right now. TI even has a reference design based around it and the TPA6120A2 (though I wouldn't recommend this design, as it has problems, OI being just one of them).
