Leave it on?

I have a large Pass XP-30 preamp and I can't find a way to turn it off other than unplugging it, and I'm not climbing behind my equipment racks every night to do that. My McCormack UDP-1 doesn't seem to turn off either. I leave my Hovland Radia Amp on all the time because it doesn't sound good for many hours until warmed up and I listen every morning. I have a Moon 280D streamer which I do turn off. I'm not sure where the logic is there. My ARC PH-7 has tubes, so it's off until I use it. I had a McCormack amp and McCormack told me to leave it on, that it's power usage was like a lightbulb when not listening to music. 

Like many, I leave ss gear on 24/7, unless i'm going out of town for some time. Tubed gear gets turned on for listening, then off at the end of the evening.

The only exception to this is the Aleph 2's I own. Those generate so much heat in my small listening room they get treated like tubed gear.

@audiodwebe Yep I turn my Aleph 1.2's off nightly after listening – the heat but also the electrical bill.

@au_lait “…. the heat but also the electrical bill”.

As @vair68robert said previously in the earlier days of this discussion…..

A single amplifier at the national average KWh rate, consuming just 85w powered on amounts to $166 a year.
 

Your Alephs draw 500w each. Good job you turn them off.

Hi.some of my equipment have manufacture shut off automatic.xconsult the manual and have fun

"Do you hear any appreciable difference with your thermal magnetic switches in?"

The only physical changes were adding a thermal magnetic switch in the wall to the hot wire feeding each amp, and then removing the (pretty good - recent SR color) fuse installed by SMc Audio and replacing it with a1/4-inch, 99.9 percent copper rod that was burnished smooth.

To your question, no, I do not hear any appreciable differences that I would reliably attribute to changing out the fuse for a thermal magnetic switch.  I am not surprised.  However, I do get to turn my amps off without unplugging them or turning off the breaker at the main electrical panel so I am happy with the win. 

@mitch2 ,

I score it a win if it didn't degrade the sound, plus it was a cool things to do!

You know this, some things can be left on all the time, and some things can't. I wouldn't leave any tube gear on all the time unattended, on the other I think solid state could benefit from being powered up for long lengths of time. It could be true that the act of turning SS on and off a lot with the in-rush of current could increase the risk of component failure. 

I turn everything off after each session. I have a PS Audio P15 and part of its design is that it soft starts everything so there isn't the harsh inrush of current that could be damaging. The other reason is that my system was hit by lightening so it is now off and unplugged from the wall when I'm not listening. One strike is all it takes and that is the end of your equipment that you are trying to get extra life on. I also don't need the extra heat and electrical bill with the five amps being on at all times. 

Both arguments seem valid. I myself have a 25-year-old Harman Kardon integrated amp that has been turned on and off for almost every use and is still fully functional. However, remember that heat is still the worst enemy of electronics, so I would suggest leaving it on or in standby mode during the day when you’re actively listening. But if you go on vacation or will be away for an extended period, I don’t see any good reason to leave it on. Occasional power cycling won’t harm the gear, as it’s well within the design tolerances.  My Parasound a23 PA is running 126 deg F inside the chassis and the Harmony micro DAC is running 104 deg F on the top of chassis (so could be even higher inside).  I really don’t think it’s a good idea or good practice to leave it on all the time—unless you can convince someone that the high temperature won’t cause any damage to or degrade the performance of the electrolytic capacitors inside.

I have checked up on my equipment.

Grimm says to leave the MU1/2 on and currant draw is scant.  

Weiss DAC501 consumes 2.2 VA in standby. Some think a twenty hour warm up is key. In use DAC uses 25 VA. 

AudioQuest Niagara Says leave on or off.  I keep on as streamer is connected as are low voltage PSU’s for swich and filters.   

Tubes on for use only  

The internet AI reports it Depends on priority. Best sound = keep it on (except Holliday’s or if you listen very rarely of course), Best for your wallet = switch it off. Always turn your equipment off if you are not going to be using it for a few hours (that’s not great advice) and always turn it off of you are leaving the house or over night.

Yes , for me, if away it all gets turned off  Not good if you need yr. roon core and are using remote?????

I suspect/know darn well that other things in my house suck way more juice than standby audio gear. Internet is connected to so many things and they all are on and drawing power. Kill your television. 

Given switches location on Subs turning off very unpractical. 

Plinius said leave my Class AB integrated on all the time. Their newer ones have the power switch on the back panel. My phono stage doesn't even have a power switch (Sutherland Insight LPS) - if it's plugged in, it's on(unless your power conditioner if unplugged or off).

I know it's socially acceptable to not really care about the planet anymore, but you should turn it off.

We all know that coal is now the cleanest Energy producer that's available, but still good idea to turn off your equipment.  Most ss equipment is durable enough to last a lifetime.  

Naim recommends leaving their equipment on 24/7, primarily because it allows the system to maintain a consistent operating temperature, which is believed to improve sound quality and stability over time. Leaving it on also avoided the potential stress on components from powering up and down. While some may be concerned about energy consumption, Naim suggests that the environmental impact is minimal compared to the benefits.
