pioneer:
In the process of recording and mastering a CD. Low-level signals – signals lower than LSB (Least Significant Bit) of a CD’s 16-bit system - are removed. But the absence of low-level signals causes quantization noise, resulting in a reproduced sound which is unlike the original.
Pioneer Hi-Bit Legato Link Conversion restores the lost signals by computing the original waveform from 16-bit data stored on the CD and performing re-quantization in expanded 24-bit data form. This conversion process results in a waveform which is both smoother and closer to the original than conventional technology allows.

is wohl blumige beschreibung eines 8x oversampling 24bit dacs.
wohl jeder 1-bit dac arbeitet so, egal ob von ad, ti, wm, akm usw.
