To be honest, I don't find the hifiberry products very worthy, unless you value the tidiness of having a hat instead of a second box.
A dongle instead of a DAC hat, or a USB spdif card instead of the digis are much more versatile and quite often not so pricey. It would be a much different story if the pi didn't have USB though...
