I have this, haven't tried it yet. It is planned for some cheap DAC. Connects to LRCK.

You heard wrong, both PMD100 and PMD200 are excellent filters, normally the PMD200 is even more difficult to obtain.
I will soon get another PMD100 for about 130€, so let it sit in the drawer until I need it. 😀
And you would need to program pmd200 😁 I'll obtain one and have it stashed for more free time period of my life 😁
I don't care one bit which digital filter is better. This is a thread about NOS vintage multibit DACs.
Yesterday I was soldered the diode and voltage is 4,2V. The cooler is hot only at the center (where transistor is installed). I didn't buy another cooler yet.
Maybe I'll do the same things with my another dac - add 5V on Jlsound but there is only one PSU-1 (no place for another one).
One more thing - I was told to add more np0 for feeding dac (opamps and chip). Is that necessary? Opamps 4-8(7) feeding leg and GND.

@Sorenm I tried some Panasonic Smd film caps this few days to replace those 0.1uf MKP that were occupied by Kemet or Vishay on my boards. They do sound more slightly less grainy, a tad more smooth. Difference is small, not a day and night difference.

... and acrylic are a little better. Should try the new acrylic Panasonics ones that swap the ECHU Pen line!
Good layout on that picture : the closest to the chip pins.

Acrylic from Rubicon is a little better than Panasonic, but a little bit more expensive.
But I can't guess where to use it in DACs.
These film capacitors are very useful where microfarad (>0.1-0.2uF up to few uF) range required for low (20-30v) voltages and small sizes. For smaller values NPO ceramic (up to 0.1-0.2uF) is better in the signal patrh and X5/X7 at the power.

Yes, sure - phono preamps, DAC's LPF, etc. Jus pay attention to it's limited value.
Alex.
My vote is for rubicon MU 👍🏻 But they are expensive at mouser and digi.
But, np0 are amazing little buggers too. 0603 for decouple, yes please 😁
