I used to leave my class A Pass amps on but put them in standby now. I was surprised to learn of the cost of running them for a year.
- Annual Usage (24/7): 17.76 kWh \(\times \) 365 days = ~6,482 kWh/year.
Based on a national average of $0.15 per kWh, running a pair 24/7 costs roughly $970 - $1,100 per year.
Have to balance that against the wear and tear of the on/off cycle. Might leave them on daytime/evenings in the cooler months to offset the cost of running the HVAC.
