Here's what I have:
Dedicated oversampling/interpolation ICs:
DF1704 (Burr-Brown digital oversampler, dedicated DF chip, from 2001)
http://www.dddac.de/files/DF1704.pdf
(Unfortunately, I sold my pair of PCM1704 many years ago, I think the DF1704 should okay work with other DACs)
NPC SM5843
http://vasiltech.narod.ru/files/SM5843A.pdf
(It doesn't do I2s, so that might be a big issue)
Philips SAA7220 A or B
(in use currently in several active projects, couple with -- what else -- a TDA1541(A))
DACs:
PCM1732 (a combo of HDCD filter + delta-sigma DAC, from 1999)
https://www.datasheetcatalog.com/datasheets_pdf/P/C/M/1/PCM1732.shtml
AD1862 (pair)
PCM1792
PCM1794
PCM1795
PCM1796
PCM1798
CS4398
Philips TDA141 (A)
Philips TDA1543
Philips TDA1545A
Philips 1387
Philips TDA1305T
SRCs:
CS842
etc.
Receivers:
CS84xx (12, 14, 20)
Adapters:
Xmos and "Amanero" USB-I2S boards.
============
Initially, I just want to breadboard some of these devices together -- quickly. And want oversampling/interpolation and/or even "upsampling".
I want the breadboard unit to be functional -- doesn't have to sound spectacular. I can work on that later.
My ultimate combo wish is to pair the DF1704 to AD1862 (pair). But I want to stay in the I2s domain because my main input will be USB-to-I2s. And I think the the AD1862 only allows Binary Two’s Complement, MSB-first, right-justified audio data (input). Also, the AD1862 has to be trimmed and and then be followed by I/V and LPF. And all that makes for a messy breadboard!
Yes, I do realize that several of the standalone DACs have built-in DFs. But upstream DFs and SRCs can, nevertheless, "upsample" (condition) the digital data so it enter the DAC more ... cleanly .... yes ???
About SPIDIF:
Well, my Linux PC and Laptop -- my main file and Foobar source -- can't output SPIDIF ... but if SPDIF is the best sonic option (and not USB), then I'll have invest in, say, a high-quality PCIe motherboard mounted SPDIF adapter.
Looking for options ... suggest some in replies. Thanks!

I've successfully operated TDA1545(a) and TDA1387 with ASRCs CS8421 and AD1896 - didn't sound bad at all.
Forget SPDIF at all unless you've got good reason to do so, in my case I own a RME DigifaceUSB that only has optical SPDIF in/out (and is the cheapest way to enter the RME world).

No reason to breadboard the AD1862 unless you really want to. Miro's board is small, clean, and well equipped for mods to use it in lots of different ways: https://www.diyaudio.com/community/threads/dac-ad1862-almost-tht-i2s-input-nos-r-2r.354078/
It's not hard or expensive to build a good-sounding board, then you can concentrate on breadboarding the digital domain stuff that you want to experiment with.
