Interesting...but, it has only 16 bit and the output is single ended so can generate problems with noise.
AK4490 USB Dac with dsd support.

You can just read what others say about it...Most probably you already know what you want from a DAC.

If I want to use this DAC chip it seems that I need to do a completely new project and whether I quit galvanic isolation or galvanic isolation will become much complicated.
There's a denon dcd 520AE for 20 pounds in a charity shop, i'll probably be able to get it for 10 pounds next week. Looking for its schematic i found there are 2 variations with slightly similar schematics, one of them being Denon 720 ae which had headphone output and a different 32 dac chip.Look for their service manuals, it's free on electrotanya.They use 32 bit dac chips too, not the best of them though, but v-out.I might buy the 520 ae and send you some inside pictures with the pcb art-work.
All DIR chips that I verified were not capable of 32 bit, only maximum 24 bit, so to use maximum resolution of the DAC I need to find a DIR chip that support 32 bit.
If you really need 32bits, then you won't be able to use S/PDIF or AES/EBU serial interfaces as they're limited to 24bits maximum by design. As far as I'm aware even USB Class 2.0 is limited to 24bits too.
No, I don't need 32 bits because the limitation of the interface and exactly because of this I do not care if the DAC is 24 bits or 32 bits.
A question: is really a need for a SRC module or is it only a nice to have?
Which would be the advantages and disadvantages of a SRC module?

Starting from the pictures already posted where you can see which connectors I used, I want to ask you for equivalent or similar versions but of better quality.
The most important thing is to find a variant for this connector
https://www.tme.eu/ro/details/fc684206r/conectori-optici/cliff/orj-6-fcr684206r/
because the dust protection door broke very quickly and the optical fiber doesn't stay either, but falls/comes out immediately.
I also need some stacked RCA connectors (to take up less space on the PCB). I only used recovered connectors (I couldn't find new ones to buy) and there are still random problems with the lack of connection for the central wire.
And because I'm doing a complete redesign and I want to add a bluethootch module and I need a solution for the external antenna of the box and an AES/EBO input and I don't know which connector to use for AES/EBO.

Could be those connectors are not longer made? If not, how can anyone help you?
Maybe you need to make some kind of connector box that you can attach to the outside of the dac/cd_player/whatever box, and that uses currently available connectors?

Not. I am now working on the redesign and these connectors gave me small problems on the old version and I am interested if there are better versions.
Because they are being redesigned, the new connectors do not have to be identical, but only functional because the board will be redesigned anyway.

No, UAC2 is not limited to 24bit.
Even if USB receiver is configured for 24bit for PCM formats, it always use 32 bit for Native DSD.
Oh sorry, just noticed I replied to a 4 year old post...
Does anyone really know any better plugs than these? In particular, the connector for the optical fiber is weak because the fiber does not stay and falls by itself.
Doesn't look like there are better choices unless maybe you are looking for some expensive audiophile connectors. Even in that case, don't know if they have stacked versions. Probably makes most sense use to an un-stacked SPDIF/TOSLINK optical module.
Thank-you. Yes maybe a nonstaked version can be find better versions but I do not have space for all in this case.
