Hi, this is my first post since receiving my Ultra last week. I'm very happy with it, but I have one query about the phono input. Does anyone know what capacitance the phono input presents? I'd expect a typical value of 100pF, but is there a definitive spec?

There is no spec so far. 100pF would be ideal.
Unfortunately, many cheap phono inputs are plastered with capacitors to help with RFI requirements. Worst examples go as high as 560 or even 900pF.
I tested the Ultra's phono input with my AT V540ML which is not exactly known for its low inductance and did not hear the typical HF peak found with too high input capacitance. But it could also be my aging ears are no longer trustworthy.
It would be nice if WiiM could clarify this topic.
