Today, the last two serial regulators in the DAC were replaced, two ADP7118 for DIR9001 were disconnected and Walt Jung shunt regulators were connected instead. These are also the first such regulators for 3.3V.
I am very satisfied with the result, which is only a confirmation of the simulation in LTspice, where the difference between these regulators is clearly visible. It's the same thing if I compare LT3042 or ADM7150 with this shunt regulator.

Hello Grunf , I am also interested in the fashion of shunt regualtors , but for few milliohms differences between the series and shunt can we be sure it's an real improvement , and are the measurement stating so , by measurement I mean at the dac output , I haven't found anything about it , only subjective thoughts
is there a theorial and physical reason for such an sonic improvement
.

.
Those milliohms differences are exactly in the HF area, above 100kHz.

@fabrice63, A shunt regulator makes no sense with batteries due to high losses.
For example; my shunt reg for 8 pieces of PCM1702 has almost 10W dissipation or the shunt for AD811 has 6W only because of higher voltages.
