Polymer can be great here. But do take note of Abraxalito's comment here:

For stability, replace the 0 ohm jumper in the supply lines with 2.2R. But i do have them in a few of my project with LT1963 regulators and things are fine without inserting the resistors.

And Sanyo makes OS-CON capacitors as well. I don't know how they are for audio, probably there are different opinions and experiences.

Os-con is just a trade mark of Sanyo organic polymer caps, and was sold to Panasonic in 2010 or so.
I have used both Sanyo and Panasonic.
For these DACs I used ELNA Silmic (analog part) and Nichicon (digital part and PSU2) while it was available here locally. I still have a certain amount of it for AD1862 (DAC board and PSU2) and I'm done. 😎

Are these still the most up-to-date references for putting together the Miro TDA 1541?

@ElArte Yes they are the most up-to-date 😉
You can experiment with this converter for TDA1541A https://electrodac.blogspot.com/p/i2s-to-tda1541a-converter-tutorial.html
(in that case IC1-IC13 are not connected and converter is connected to the appropriate pins)

I still have PCM1702 in that plastic box, somehow it worked out nicely over time and sounds better. Those who use Elna Silmic say that they require a lot of work time to play it properly. That's probably what it's all about. Maybe now I should go back to PCM63, and there's Elna Silmic too, not worked out yet. 🤔
And AD1862 are waiting for me to find some time for them. 🙄

Elnas are a pain to listen on signal path, for the first ~100h, sounds like a cliche number, but it is true. No bass, sounds muffled, closed. Crazy. Then sunshine breaks out, and you enjoy probably the best available elco on signal path. But on decouple, i cannot comment. Too much factors to single it out.
Yes, NEVER.
after 30 years of burning in, Elna Silmic II still sounds bad to me... Being NLA was the best news of the XXI° century for audio diy enthusiasts !

I like the bold definitive diyiggy... I'm thinking I agree... so what do think about the lower capacitance Russian Teflon's in the nFarad region? ... and maybe some ceramic trimmers?
Each cirsuitry needs its own tests, so no definitive ratting about a particular cap. This is just I never had sucess with the Elna Silmic II but in serie -++- to mimic a bipolar for DC blocking and high pass filter in the 90s when i was tweaking old Philips and Marantz CD players.The browner Silmic that are darker but less detailled sounded better to me and were used a lot by Sony IIRC.
I made a rapid test with the AD1862 and few caps but mainly tried a dozen of different I/V resistors in this thread. The difference was significative. It was with an opa1656.

I replaced that Elna caps first in a Marantz CD63 as soon as the warranty ran out. By the way, I also kicked the HDAM module out of the game. That is heavy nonsense. Instead of the original JRC OPAs, OPA2604AQ came here. I put different plastic caps in parallel, replacing Elna Silmic (2pcs back to back) at the output. Just yesterday I replaced that Laser mechanism again, these Chinese VAM1201/2 usually works well, but for a short time. 🤣
It is now an outdated device, but I listened to music quite a bit with it. Then came DDDAC1794 and Pioneer DV300 (modified) as CD transport. The Marantz is listened to occasionally, mostly as a CD transport.

The Silmic's have sounded rather strange to me, as a means of "voicing" not to my taste. Some of the Black Gates have worked well, though take a long time to burn/settle in. Currently I am working on an I/V for a PCM63 based DAC that is using a 1n2 Russian teflon in the feedback, hence the question.
