Not talking standby mode either. I suspect it's the minority though.nopiano said:Hopefully they are too stupid to realise that cleaners are used for a few minutes but hifis can be left on for hours! Soon we'll be heating kettles with candles...busb said:The power consumed by vaccuum cleaners is vast compared to the few remaining Hi Fi systems so don't be too surprised if Hi Fi remains completely under the radar of commissioners!Alberich said:I suppose I'm trying to gauge what is the level of likelihood that future fans of class A will be deprived that choice. Future generations of audiophiles may have their hands tied on this. In 100 years from now audiophiles may not have the luxury to choose class A, and for better or for worse, class D and no doubt other topologies, will be the mainstay. Class A will become something uttererd only by ageing audiophiles and connoisseurs of vintage kit and ultimately resigned to history.Benedict_Arnold said:I shall consider buying a Class D amp. Until then it's Class A or no class at all. My little hi-fi isn't going to kill the planet. After all, the brats almost certainly burn more juice leaving the pantry light on than I shall ever use listening to my stereo.
Look at the EU energy commissions ruling on vacuum cleaners for precedence. Who knows what regulations will have to imposed in the future. Some may find this tone alarmist in nature but be warned lovers of the pure current, the end is near!
Most components fail because of mechanical reasons, and it is the thermal shock and inrush current at switch on that causes them to fail. Electrolytics are an exception and will dry out quicker in a warm environment, so if you have a class A toaster, it would make sense to keep it off when not in use.
