Green, Eco Friendly Class A Monoblocks



Every time the power goes out where I live, I am reminded how much my life and interests revolve around electricity.

So as I contemplate a new house, with a dedicated circuit for audio equipment, I am wondering if there is yet any sustainable, green, or eco friendly technology which could supplement or perhaps even meet the demands of the hungriest audio and video systems.

Could anyone please comment on the latest solar or alternative energy sources which could meet the demands of a traditional high end audio system?

(Not as excited about switching to class D amps and/or renewable iPods.)

Thanks and hope this is of interest to others.

Karan Acoustics amplifiers might fit your criteria for 2-channel. They do not draw much current at idle. They also do not get hot.
If I might point out another aspect of 'green', we have an update program that allows any of our older amplifiers or preamps to be updated to the latest level with full warranty reactivation. This helps keep the product from entering the waste stream, prevents obsolescence and supports the resale value.

If you want class A, which IMO is the best-sounding way to go, to keep the energy aspects down you will want a speaker that is high efficiency so you won't have to make a lot of power to run it.

Even with a high efficiency speaker though Class A is still not "green" compared to Class D. Right?

My Class A mono blocks use MUCH more electrical then my Class D amp I built.

I used one of these: http://www.amazon.com/P3-International-P4400-Electricity-Monitor/dp/B00009MDBU
Atmasphere - average music power delivered to speakers is very low. It is in order of few watts (few percent of max power) while class A takes up to 8x max power. Class A take the same power all the time. When delivers power to speakers (few watts) it dissipates less in the heatsinks.

Cwlondon - Solar panel for class A won't change anything. It is still "polluting" component since you could return this solar energy to grid and reduce emissions.
Same is true for hydrogen - it is very "dirty" fuel since it wastes a lot (90%)of energy in making it using electricity. The fact that energy might be clean (solar, wind etc) doesn't mean anything since, again, it could be returned to grid instead to reduce emissions. Fortunately it will never see daylight since selling hydrogen would be the same as selling dynamite without permit.
