I looked up the specs for the Adcom 555se and it is specified at consuming 72w at idle. So depending on frugality, you could leave it powered on continuously.
By comparison, my W4S ST500 consumes 28w at idle. I leave it powered on all the time. The preamp in that system is a Manley Shrimp and I never receive any noise when the preamp is switched on or off.
So, that’s an option to consider.
Doing the math for 72w continuous for a month yields roughly 52kwh consumed. Electric rates vary, but let’s use 22 cents per kWh which would cost you $11.44 per month whereas an ST500 would run $4.44 per month. These figures are idle consumption only. The more you play, the more you pay.
Class D is more efficient while playing as well.
