Can you hear a difference or is it just infernal bias?
If you are the least concerned with wasting electrical energy I recommend a Kill A Watt. All other methods of calculus are merely guessing.
Warm Up Time/Cost of Operation
When I have solid state gear I will leave it on 24/7. For amplifiers this was no big deal and with certain amps previously I could hear the differences between a cold start up and 3 days of power up.
A year ago I bought a pair of Classe Omega monoblocks. A bit ago the wife was commenting on our electrical bill. I could not find online specs for power consumption but this morning I located the manual.
Consumption is listed at 706 watts. I assume this is per amp and hourly consumption. Electricity here is 12.6 cents per KWH. A calculator shows the cost of 24/7 on ad being $126 a month.
It's a bit wasteful to idle like that so I am planning on switching off moving forward. But I am wondering what should my plan be moving forward.
Thinking I will turn them on when listening in the morning casually, shut them off while at work, turn them on when I get back, and shut off when I go to bed.
Anyone have experiences running big amps like mine in this manner? Thoughts and experiences are greatly appreciated.
