Not me insisting, but convolving 8 analog channel outputs per RPi.
I am hoping that the sort of power reduction measures you suggest may help it run "more fanless" silent most of the time.
Would CM5 be easier to reach that goal?

Of course the GPIO header is not RPi compatible. But the 8ch Hifiberry hats (both DA and AD) require no control, they just contain 4 stereo DAC/ADC chips with no I2S/GPIO/SPI control lines, only connected to I2S lines. If you enable 8ch I2S I/O and connect the correct pins, they will work on any SBC, no need for RPi nor their "driver". I put the "driver" in doublequotes because that driver just configures the I2S interface, does no control of the chips on the hat. That can be achieved by appropriate device tree config on any SBC with 8ch I2S.

My understanding is that the reason for an e-Marker chip is to indicate that the cable is capable of more than 3A. But, you need a power supply that will provide 5V/5A. I also cannot find one other than the ones specifically made for the Pi 5. All of the ones I have found include their own cable, not detachable from the wall wart.

What components do you have attached to, and drawing power from, your Pi 5? The 4GB version of the Pi 5, with the CPU at full load on all 4 cores, uses about 8.8W. If you can determine the power consumed by the other components drawing power from the Pi, add those powers to 8.8W to see where you land.
I suspect those generic adapters are not 5A capable, by the looks/thickness of them, but probably they aren't emarked either...But as they are quite short, maybe doesn't matter much, while they don't melt, that is.

The wire on my adapter is short, probably around 4". I don't know what size wire they are using, but for such a short length 22 AWG probably has resistance low enough to be adequate for 5A. I wouldn't use 22 AWG for a 3 ft. run, though.
But, whether someone really needs 5A depends on their use case. In my setup I only have the Pi 5 with a SMSL PO100 2024 digital audio interface. The PO100 draws 0.5W. So, even if I had all 4 cores of my Pi fully loaded, to which it never comes anywhere close, I would be drawing around 9.3W, so less than 2A of current.
If someone has all sorts of peripherals connected to their Pi 5 and really does need every bit of the 5A, they could get an adapter and measure the resistance to see if it will work, or they can run it and see if it starts to get warm. Alternatively, they can provide power to the Pi via the GPIO header and only use the USB C port for data.
what i did was USB PD decoy IC set to get 15V/3A that all of my wallwarts can provide -> 5A capable buck converter -> rpi 5 header. The 15V powers other stuff but the overall power is more than enough. I know this is not a solution for everybody as one needs to build a dedicated PCB but it allows to power all the other stuff i have on the board with one single regular wallwart.
What i would recommend otherwise to keep all USB free if high power is needed is a regular 5V PSU connected directly to the header. I remember going through the rabbit hole of the current specs of the header pins but i dont remember exactly what i found. But i am sure if i ended up following that route is because it was "suitable enough"
Thanks for the stats, that's quite extensive use of the little thing.
If 5B is about 2.5 times faster than 4B, for that workload 4B would use 50% CPU and power consumption would be about a half or less.5B is not a bad device, but IMO if an SBC needs active cooling, it's intended for different use than passively cooled ones.

Sample rate? Bit depth? Taps?
96kHz, S24LE3 , Taps i need to look on my Screenshots i did long Time ago, i have saved my rephase Settings i guess, need to loock at!

You need to be creativ than you could use it passive as well but in a biger Enclosure for ITX PC like thisThanks for the stats, that's quite extensive use of the little thing.

or anything like this, sure you need to adapt it or may be you need an CNC Part to make or order anywhere like PCB way or so

I have my Pi 5 in a passively cooled aluminum case. It runs cool.

Note, though, that the aluminum case severely limits the range of WiFi. I use the Ethernet port.
I found this screenshot:
8 CHannels in and 16 Out without Crossover filters addad only pass thrue with some Delays for SPDIF and ADAT Connection to get all Signals synced from 2 Motu UL MK5, 0,7% Processingpower used.
Thats the Routing without Crossover only with Delays:
BTW i am an idiod i use the RPI5 also passive cooled, looool but vorgot about , will find what kind of case this is also M.2 SSD is Passive cooled on top used half off an second RPI enclosure for that (be creativ ):
Thats both Cases from EDATEC, bought the open and the closed one, used the closed one for the RPI5 and the open one half for the m.2 SSD .

First try was aktiv thoo but you will never hear it in a Case, probably only if you stay 0,5m away or so.
