If you can turn it on/off with the remote, it must be in "Stand-By." It could not respond to the remote if it was really powered off.
I guess it depends on what you mean by "Standby". Expanding on what Elizabeth says.
I am not saying that the following applies to the Sony, but provide this as a different example of "Standby".
With my BAT VK50SE amp, I can put it into Standby by pressing the Standby button on the front of the amp. The little blue light lights up, and the valve heaters are still running (probably at a lower current) but the B+ is turned off. To fire it up again to operational mode, I can press the Display/POWER button on the remote, and it goes through a 60s cycle and comes on stream.
In addition, I can hold the Standby button on the pre-amp down for 5s or so, and it turns completely off. The Standby light goes out and the tubes go off, and it goes cold.
But the IR receiver for the remote is still working, because I can fire it up from being off with the remote.
I would have to unplug the power cord to completely disable it.
So perhaps there can be three operational levels if we take the remote circuitry into consideration.
