Earth Day, turn those amps OFF!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The first Electric Fridge and Electronic design Audio device were produced at very similar era, with the Fridge being a well-established mainstream product by the rhe the audio device was first marketed.

The Fridge, and the later available Freezer, that came to the market later than both the fridge and audio devices, are both designs that are with their design intent to be continuously on, as this is the design that keeps the stored food stuff for an extended period to not perish.

Even the fridges are known to have caused a fire in a domestic environment. The initial cause of the fire in the link is a Fridge /Freezer catch fire.

Fridges and Freezers are approx'100 years in progressive design to be permanently on 24/7 and not catch fire, but guess what; they do!! 

Audio devices are not with 100 years of progressive design to be kept with power on as a 24/7 appliance is!!!!

The only other permanent power-on appliance I can think of in my home is an electrical supply to a water boiler/home heater, where this type of design is currently near 140 years of being a progressive design to prove the fit for purpose of the supplied products, which are scrutinised by regulators and industry bodies before making their final stop in the market.

Does an audio-related device receive the same attention???  

Power Off is the simplest of safeguards, where audio devices are the subject.

@pindac I initially said: 

For your safety, never turn your [audio] gear on.

And you said: 

Power Off is the simplest of safeguards, where audio devices are the subject.

It seems we do agree! 😃

It's not about agree/ disagree; it's about assisting with showing others how a forum can influence decision-making that has the potential to substantially alter one's life experience, in a way that would not be wished on anybody.

Power Off - Sleep Well in Your Bed.

I haven’t read but the first couple and last page of responses, and I certainly don’t have full knowledge of the OP’s overall habits as concerns environmental concerns.  But, and jus’ sayin’, my experience has been that, almost without exception, I have found that I can always find ways to express my concerns about the environment that elude even the most “environment conscious”.  Like I always tell my kids, it’s all about balance.

I have vintage second system which at its heart has a Roksan Platinum PR15B & ST1308 Pre and Power. If it were not for the Auto Signal Sensing system where it powers into low state until a signal is detected, it would cost me around £180GBP per year to leave idling, in reality it costs me about £30GBP.

However, I never leave my main system EAR Yoshino 912 all tube/transformer driven Pre Amp on, it has some natural designed in functions that make it inherently a soft start system and neither do I leave my Tube Power amp powered on either fully or standby. Tube life and component heat stress is a far more important factor for me and more than out weighs any unconvincing benefits sonically of keeping everything in a fully powered on state. It has a relay bypassed soft start system too.

Typically my pre amp reaches optimum 15-20 minutes after switch on, the same goes for my power amp. I use the REL’s standby system which works well and I have heard it helps modestly to preserve their amplifiers in the same way as the auto low power state for the Roksan Pre & Power in set up 2.

So when I want to listen to my main system. I switch the system on 20 mins before I start listening usually with low level signal playing from the streamer.

I leave the power supply to the Lumin X1 powered on which is again in the region of £30GBP per year.

So I feel I have struck a reasonable balance of system preservation and reaching sonic sonic stability and optimum performance states, without taxing my system from cold and having to wait too long.
