Electric Bill

That's about 40kW daily for audio only and so 1.2MW monthly. Enough to juice up the band in the 1000 seats venue. Your room is a-bit smaller.
Do you keep all of your amps on all the time?
Anyways, you are the champ so far... I'm somewhere between $7...15 monthly out of $80 bill that most goes onto climate control and home appliances.

why not you can consider the electric bill and turn off your equipment when you're not listening. it's only half-hour the most of worm-up time that you can actually listen to background music and worm-up components even faster.
becides running on all the time tube phonostage is not wise at all, because the worm-up time is in 5...10min. if your computer is on all the time and connected to internet, you may catch the unwanted automatic updates or even malware. also the processor time is finite and usually it blows when processor fan stops...
you can consider electric bill, you can consider the safety of your equipment and take few seconds to turn your components off.
