I just want to check if Nuprime's xlr contacts are connected as follows or not.

pin 1 = ground
pin 2 = hot
pin 3 = cold

That is the universal standard. I would be very surprised if their gear did not conform to this.

Some European and Japanese gear use a different pin layout with pin 3 being hot.  My luxman dac is wired this way while my BAT and Pass gear is standard pin layout.  All my gear has the ability to switch phase on XLR's.

Eric, i hadn't problem with STA-9.

Usually if connection scheme is different from common - manufacturer makes remarks on rear panel.

But pin 1 is not ground. Pin 1 is only the shield, it should only be connected to the chassis at the XLR connector.
