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.

Luxman Class A owner here, 400 watt dissipation when on. Usually allow 30 min warm-up; leave on most of the day on weekends.  Keeps the room nice and warm during the winter.

There really is no need to run an amp 24/7 unless you’re listening to it. Apart from the electricity usage, there’s too much wear and tear on the components in terms of heat. I know A lot of audiophiles leave ss gear on but not me. That’s my 2 cents.

Wow! That is some monthly bill, like going to a concert every day! So I got tho thinking, can that actually be true! Yes I know, the mind of an engineer goes in the wrong direction for some. Anyway, for only $14 on Amazon USA, you can get a a SURAIELEC Watt Meter tool that will measure the electricity of any plug in appliance. I'm getting one so I have something to do this winter! If you do it, let us know in a new post what you find.

240 watts is still a lot of heat.  This costs you twice in the summer since you put that much heat in the room and then remove it with your air conditioner.  In the winter, you get some of it back on your heat bill.

that much heat also degrades components.  As a rule of thumb, electrical components that run cool will last forever and the warmer they are, the shorter thier life.

Turn it on, go to the kitchen and get a drink sit down and listen.  Maybe it will sound better after a while, enjoy.

3 Tube amps here....Must be turned on and have a signal going thru them for at least 1/2 hour to perform properly AND YOUR SPEAKERS need at least 30 minutes for their voice coils to warm up and expand to function to their highest potential according to Steve Deckert.....He's Right.....30 minutes of warm up on ALL equipment to reach full potential.
