I believe you should remove the regulator and the 2 inductors L1 and L2. I couldn't desolder so i ripped them with a plier. Not too clean, but it worked.

It should be good, but: you still have the 2 noisy inductors and the regulator on the pi. If you remove them and use this, it might not work. And the pinout of pi3 doesn't have 1.8v.

Thanks for the instruction. A late comer here who modified a RPi3 model B with linear PS for 5V, 3.3V & 1.8V.
The audio improvement is enormous!
More dynamic, more power, more details, more engaging!
I am extremely happy with it.

Now someone mentioned about the C97 / C98 capacitors modding behind the USB unit.
I am eager to try it out and like to know in detail what to buy and how to install it.
I am a fresh DIYer and hope someone can help me out.

Thank you again.

My gear list:
RPi3 model B;
50VA transformer 2x9Vac secondary winding;
LT3045 regulator module to go down to 8Vdc;
then LT1963 regulators for 5V, 3.3V & 1.8V;
WD 500GB SSD;
EDUP wifi dongle;
