Hey,
i decided to DIY my next DAC and kinda wanna share my jorney here and kinda wanna document it for myself...
i will keep the parts list updated here:
-------------
Case - https://modushop.biz/site/index.php?route=product/product&path=171_229&product_id=158 with inner baseplate for 70 euro
EMI filter - https://de.aliexpress.com/item/33030666632.html for 12 euro (nice pcb layout)
Transformers - toroidy audio grade
usb to i2s - either jlsounds or amanero derivate
dac - probably jlsounds ak4493
-------------
i might also do some pcb"s on my own, the rectifier board seems easy todo and probably better than chinese bought ones..
still alot to go... stay tuned

i think the rectifier board is 98% finished -> https://www.diyaudio.com/community/threads/universal-rectifier-and-filter-smoothing-board.411234/
together with this goes this board which need to still design the pcb: https://www.diyaudio.com/community/threads/universal-lm317-adapter-board.411248/
probably will use one for pregulation and one for each output, about the regulators im still unsure what i will go with but this board will be kinda optimized specially for sparkos discrete regulators, so i definitely will test them at some point, im a true believer of discrete opamps so lets see...
i also asked at toroidy what a custom transformer with 6x 7V would cost ... this would save me from buying 3 seperate transformers... the case is quite large but i dont think that large... 3 would fit in a row, if i wanna have some room for the emi filter probably 2 transformers max + emi filter in a row is best to keep the build tidy...
