Vintageflanker , a short question. In the cheapest SMSL PO100 I see only one clock crystal on the internal pic. In Douk U2 there is three.
One for 44,1 KHz, 48 KHz and ( I guess ) DSD signals.
Using only one crystal as in SMSL PO100 should be optimised for either 44,1 KHz or 48 KHz , and maybe not both at the same time ? I dont understand, but maybe there is no problem.
I know to little about xmos chips but maybe there can be implemented SRC that dont show any artifacts at all , even if the source material are 48 KHz and the crystal is optimised for 44,1 KHz .
Is there a measurable difference between 44,1 KHz input signal or 48 KHz signal in the SMSL PO100?
I write this because in history, there has been some USB/spdif interfaces that show different results depending on the input sampling frequency .
Edit: I found this :
