You write that you have never had audio equipment in your life.
It is known that the louder the more energy, but I do not know people who listen to music at 100% volume on decent equipment.
As a rule, at 50% it is loud enough, and if someone wants to splurge, he can give himself 75% but for a moment, not for the whole day, because sooner deaf, unless he is already deaf
Generally, for me, loudspeakers with typical listening to music do not consume so much energy that it would be crucial in bills but it is worth checking how much the power supply gets on the armed mode, because if it is connected 24h it may be that it consumes relatively much energy unnecessarily when This power supply is completely unnecessary.

Can you read with understanding?
I gave an example of my power supply from the Creative computer speakers to show that the standby power supply gets almost as much energy as when playing, which you ask at what volume level, and I said that in this context it does not matter, because it was for the very fact of relatively high power consumption in standby mode.
The meter will show the truth but I bet on the computer as the most power-hungry gadget and it has a key share in the cost of electricity if it works for a long time during the day.
@ridiccv You should look at the actual energy consumption, not on the forecasted accounts, therefore it would be worth knowing the actual consumption of kWh in a given period, so that after the change you can compare them. Now we have the winter period, so we will use the light longer, generally in winter the consumption is a bit bigger than in summer, so you have to take into account, because possible savings on one can be used for more light and you will end up with similar bills.
