Just for general information: in response to MeJames' request, we also found out that these pin assignments are the I.E.C. 268 standard pin assignments for XLR - which is used by 99% of the components out there. We also used a voltmeter on the XLR outputs of the Audio Aero Capitole mk II itself to verify this is indeed the case. It is.
In conclusion, the Audio Aero Capitole Mk II should be able to be directly connected to the 99% of all amps (and probably 99.9% of all high-end amps) out there that follow the IEC standard, using ordinary XLR cables.
