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.

Your question got me curious so I decided to measure my XA30.8.  In standby mode, with only the little blue LED light on, it measured a mere 0.3 watts.  Perhaps it's powering little more than the LED in this mode?  When turned completely on but with no music playing it measured about 265 watts.  With music turned on and at a volume higher than what I'm comfortable listening to I got it up to 290 watts draw.  I suspect the 375 watts is calculated based running it flat out at maximum possible power output.

When I'm not listening to it I leave it the 0.3 watt mode.  Once fired up all the way I find (and have read) that it take up to 1 hr to be fully warmed up.

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.
