TDB... lol. Fitting, no?

also just because its 24-bit doesnt mean it cant be well implemented. take for example the dpa d:vice which is arguably one of the most adequate implementations of a basic pre and AD for our purposes. it uses the AKM5552VN which has 115dB of dynamic range
https://www.akm.com/content/dam/documents/products/audio/audio-adc/ak5552vn/ak5552vn-en-datasheet.pdf
a 5572 which still has relatively low power consumption gains 6 dB on this
https://www.akm.com/content/dam/documents/products/audio/audio-adc/ak5572en/ak5572en-en-datasheet.pdf
a 5578 with the channels summed can gain 6dB more, albeit being probably at the practical limits for power consumption
https://www.akm.com/content/dam/documents/products/audio/audio-adc/ak5578en/ak5578en-en-datasheet.pdf
good IC pres are cheap and common but it really depends on how much board space they can devote to a good analog gain stage. cleaner ADCs reduce the need for analog gain stage to an extent
all of this hits up against the wall of EIN of about 131dB. which easily fits into a 144dB 24bit container
