Will my electric bill go 'sky high' by leaving my electrostatic speakers plugged in all the time?

No. The electrostatic portion of MartinLogan speakers will only draw a few watts (please refer to the specs for your model). There is circuitry to turn off the static charge when not in use; however, actual consumption will remain close to the same. The primary purpose of the sensing circuitry is to prevent dust collection on the electrostatic element. Models with powered woofers systems draw more power duing use, but when not in use will turn off the amplifiers to reduce power consumption. Upon sensing a signal it will take a brief moment for the woofer amplifiers to power up.
