Really? Do you have a citation for that?

Are you talking about software virtual analogs (plugins on standard OS inside a typical DAW) or hardware virtual analogs (DSP firmware)?

Sounds like you're talking about the DAC only, which takes input at 192 kHz PCM and internally calculates delta-sigma at 64x oversampling. There aren't any 24-bit DACs that run at 12 MHz. I've not seen any audio hardware running streams at 12.288 MHz conversion rates.
