Recommendation for SPDIF out. IQaudIO vs Hifiberry vs allo

Hi,
I am looking for a Digital out for my RasPi 3B+ (Volumio)

These two boards seem to be quite good. Which would you recommend?

iqaudio.co.uk/hats/48-pi-digi.html
or
hifiberry.com/shop/boards/h … -digi-pro/

Edit:
I just found this:
allo.com/sparky/digione.html
or this…
allo.com/sparky/digione-signature.html
These are getting expensive… :-0
Edit End

Or do you have a better (for the money) solution?

Thanks for the help.
Best.
Fabian

Just want to throw this one in:

Same as the HiFiBerry Digi+ !!!
