Cost of Keeping Components on All the Time?


Hi Everyone,

The original poster in the thread below asked whether he should keep his equipment on at all times. The answer was pretty much "it depends."

My question is more about cost: I'm curious if anyone has noticed an increase in their electric bill from keeping things like SS power amps, tube amps, AVRs on all the time. Of course I realize that too would depend on various factors, but I'm just looking for some overall guidance. Are we talking a few bucks a month, or more/less? My components are listed below to give you a sense of the scale I'm talking about. I'd prefer to leave everything on all the time except when I'll be away overnight.

Logitech Squeezebox (for streaming WAVs from my PC)
Cambridge Audio DacMagic
Cary SLP-05 (for stereo pre)
Adcom GFA-555 (for stereo amp)
Arcam AVR-600 (for HT/surround)
Oppo BDP-103 (Blu-ray video and SACD)
Vandersteen 2ceSig IIs (mains; bi-amp/bi-wire capable)
Vandersteen 2W (subwoofer)
Vandersteen VSM-1 (surrounds)
meowist
Benchmark DAC1: 10W
Rowland 102: 10W

20W * 730hrs * $0.06/kWhr = $0.876 per month

That is a very healthy ”diet”. I love it.
DNA deluxe uses approximately 60W of idle power for both channels. Plug in values in the above mentioned formulas. for 15-cent kwh will yield ~$7/mo
