Pass Labs XA 30.8 Standby power draw?


I know that purchasing a Class A amplifier and being concerned with standby power draw is a bit of an environmental friendly contradiction, but does anyone know how much power a Pass Labs XA 30.8 draws when in standby mode?  The only power consumption figure that I can find is 375 watts in operating mode.

@kalali, I know that there is a device that plugs into a wall socket and then you plug in the amplifier into the device and it measure the power draw. 
I just used a Kill-a-Watt meter which you plug the amp into directly and then into wall socket as @testpilot mentioned. I was surprised of the tiny consumption in standby.  Honestly, at 265 watts I could leave the amp turned on 24/7 and the cost at my utility rate would only be $14/mo.
You got me wondering about my Krell 300cx as I forgot its specs.Standby = 60wIdle = 175wKickin' ass = 1700wNo wonder Lake Mead is about empty.  Blame it on Krell.
Put your hand on the amp when you get up in the morning while it is in standby mode if it is cold you are drawing very little like the 0.3 watts suggested.
