Electric bill any high

My electric bill has almost doubled since I added streamer and DAC. . How can I reduce consumption?

My Spectral amp and MIT Powerbar are plugged into the wall. My Spectral CD player, Spectral preamp, Aurender Streamer, and Berkeley DAC are plugged into s MIT Powerbar.

My preamp and DAC are always on. As is the Z powerbar. My CD player is on standby. I turn off the amp and streamer.

Is there snythungvi can do or do I just have to pay the Man for this expensive hobby.
