Unless you are living in a cave, you have probably noticed that a bunch of energy efficiency rules were just proposed in the US. These cover, motor vehicles, lightbulbs, gas furnaces and gas cooking appliances among other things. Climate, health and air pollution benefits are claimed for these proposed rules.
Should there be a similar rule for audio power amplifies? There is a huge difference between Class D or similar designs and everything else. Class A and tube amps generate enormous amounts of heat compared to efficient designs. Even class AB doesn't look so good in this respect. In keeping with the current trend of aiming to maximize energy efficiency the rule would likely only allow the sale of Class D and similar designs.
Along these lines, should the most inefficient speaker designs be banned as well? Offhand the one which comes to mind is Magnepan, but there are probably others.
