About $9-$10 per month for me. My system draws about 480 watts and I run it ~8 hrs per day. My local rate is about $0.08 per kilowatt hour (it will say on your monthly bill).

My Benchmark AHB2 consumes 0.5W at standby, 20W at idle and varying amount during use. Music power is usually very low, but it depends on type of music. The highest would be for playing sinewaves. After that probably organ or heavy classical pieces. On the other end would be a Jazz trio. Music power is very low because half of the peak loudness is 10% of peak power and in addition music has gaps. Class A is different story consuming huge amount of power all the time.
Ignoring miniscule standby or idle (because something always plays - music or TV) a listen for about 6 hrs a day = 180 hrs a month. They charge me $0.14 per kWh. Assuming 50W power draw it will make
0.05kW x 180hrs x $0.14 = $1.25 a month. If you listen loud it will be likely twice that. With your system in my room it would be about $12 a month for 5 hour a day listening, not counting idle and standby for the rest of the day. When calculating energy cost remember that they charge for energy and delivery, in my case $0.07 + $0.07 = $0.14 per kWh.
Your new house is better insulated, and undoubtedly more energy efficient in every way. Don’t blame your sound system, in the grand scheme of things, most use very little power. The two big draws are heating/cooling, and the water heater. The way to lessen this is better insulation, and more efficient appliances.
Insulate the best you can, biggest improvement you will see. Great windows...
Having digs under ground and in the Attic. Both are wonderful, Dead of summer or dead of winter.. HO railroad is in the attic. The basement is the basement.. 55-60 degrees all the time.
85, to 125. per month. I’m looking at a solar trailer too. I like the idea better. Easier to maintain on the ground..
Thanks for all the input everyone. I do have one of the meters suggested above. I'm not hearing crazy dollar amounts like $200.00 plus! That would have been a game changer.
My budget is okay for now. For instance though; Had I heard crazy huge figures to run an inefficient stereo, I might have considered going with class D amps.
The main reason for the question is; major changes are in place in my life. I need to reevaluate many things including every dime I spend. I may end up raising my grandchildren in the next year or two. Time will tell. When tragedy strikes in my life, I tend to look at and question everything.
Does anyone look at their power consumption report?
I'd be interested to hear reports from tube based system owners. We're the ones who have the poor efficiency, power sucking concerns.
At least for me, comparing days when the system isn't used and days used, it's HUGE!
I can't imagine the power consumption of guys with SERIOUS, giant monoblocks setups. That's got to be a 10Kw evening at least.
