It is not possible to measure input capacitance of a phono stage with a capacitance meter. You should make your measurement with the XOno disconnected. A solid state phono stage will normally have input capacitance in the neighborhood of 50-pF without any additional capacitors connected to its input.

Try measuring the wiring capacitance and adding 50-pF as an estimate of the phono stage capacitance. For example, the phono interconnects and tonearm wiring for my SME V measure 155-pF. Try making your measurement with both the cartridge and the XOno disconnected and then add 50-pF.

Good luck,
