Surely the starting point and the ONLY relevant meter to use is the meter used by the electricity supplier to calculate energy usage.

All the other fancy figures produced by a “real power meter” are worthless.

When was the last time you turned everything off (i do mean everything - fridge, clocks, computers, TVs previously on standby, CH Control unit etc etc) to start measuring the power consunption of each element of your hifi set.

I think Jon's power meter probably does a pretty good job (ie gives a realistic value)and is a lot more convenient. Not something to loose too much sleep over IMHO

You don’t need turn everything else off.

Although turning the fridge and freezer would be a good idea.

You note the energy consumption of all the household appliances on standby. You then note the energy consumption of the household appliances and your piece of hifi equipment. Subtracting one from the other give energy consumption of hifi kit. It’s not rocket surgery.

Its always a good idea to repeat the test. If the results are the same, fine, if not start again.

I personally switch off in the summer, leave on in the winter.
