Class A Amp owners, Whats your power bill?

I was curious to see how much a cost in power a month it went up when you bought a high powered Class A Amplifier. Also what is your impedance?

I cant help but think of Krell KSA-100's for about a G that would be great for winter time (Not so great for summer). And nows the time to buy one whn some one doesnt want to deal with the heat issues anymore (Hopefully)

Any way I figure it draws 800 +/- minus watts at IDLE! how much power you think I am pulling if I run it at a mostly 4 Ohm load when playing reasonably loud?

Thanks a million

Class "A" amps draw the most current at idle, and draw less when playing music. So you are saving money by playing music if it is on.

again... incorrect

The louder you play them the more efficient they get, but the current draw does not decrease. They produce less heat when playing music because some of the power they consume is being transferred to the speaker and not being dissipated as heat in the output devices, but total power consumed does not go down.

I'm with Onemug. I own Pass XA160.5s. I leave them in standby mode and turn them on about an hour or two before I listen. They are on about 80-100 hours a month and added about $20 to my monthly bill. It is so well worth it. I love these Class A amps. It's a bit tough in the summer, but I don't have to heat my living room in the winter. And the sound is glorious.

In Las Vegas: My power company wants to raise rates because we (their customers) have cut back our usage so much that they can't afford to pay their employees.

Onemug: I attended a demo (Evanston, Ill) where Mr. Pass
was presenting his Aleph amps (mid 90's?).
I asked him about the lack of a standby switch to which he just shrugged
(What? Me worry?).
I guess the EU has got his attention on this matter.

I listen on average once per week for a few/several hours. So don't know, don't care, as long as the music sounds awesome, which is it does. That is all I care about.

Wait there will be government program cash for class A amplifier. You will have to trade your power guzzling power amp for a new efficient energy star class D amp. The gov't dealer will be required to smash the inside of your beloved class A amp for the cash credit towards the great sounding 2 dimensional sound stage newer energy efficient amp.
