@Stilian little bit late to the party I, but I am curious if the clock upgrades have been successful an what the result is ?
In case your are still looking for which clock is which freq:
X1 = 22.5792MHz
X2 = 24.576MHz
I have two Hifiberry Digi+ Pro at home, both with different, stock; the metal XpressO oscillators and a newer board with black plastic ones.
Some people prefer the Xpresso variants.
For isolation of the HB Digi I use an Allo Isolator with a small mod (https://www.bitlab.nl/page_id=130). Instead of the SPDIG/Toslink I use the I2S output. Before the isolation I had sometimes a crack or other unwanted artifacts. Not often but enough to annoy me.
At the moment I consider a clock upgrade by upgrading the HB digi clocks or replacing the HB digi and Allo Isolator by an Ian Canada Fifopi. Just to hear if there is any difference or not in my setup and with my ears.
