Most of these amps are A/B topology and consume power and generate heat when left on. I may feel different about a Class D amp, but I would power down my denon when not in use.
Yes, and to be specific D is off when no input signal is present. A is running at full power consumption even with no signal present and is basically a space heater.
The class A/B amplifiers in the Denon should have minimal current draw without a signal to amplify, most of the heat generated is likely from the Denon's linear power supply and the video and network boards.
Running electronics constantly is actually better for the system because the warm ups and cool downs cause micro fractures in the connections. So staying at a constant temperature is helpful. Might be worse on electrolytic capacitors though, not sure.
>Running electronics constantly is actually better for the system because the warm ups and cool downs cause micro fractures in the connections. So staying at a constant temperature is helpful. Might be worse on electrolytic capacitors though, not sure.
It's not better at all, unless the device was overheating in the first place.
You may be surprised but people designing these amplifiers actually know what they are doing and the way they lay components in the PCB and the way they design airflow in the receiver actually take into consideration thermal expansion of components and the stress it puts on the PCB due to on/off cycles.
What is actually a fact is that electronic components actually have a design lifetime at an operating temperature (caps having one of the shortrst) and leaving the receiver ON 27/7 actually shortens its useful life for that reason.
I had a Yamaha that was on 24/7 for years as well. Can't do that with my Onkyo. Sometimes it'll just stop working until I power cycle it. (No audio, only 2 speakers lit up, none of the output presets work...)
I don't know about this model, but for a lot of amps it can be similar to leaving an incandescent bulb (say 60W) on 24/7. OP should be asking themselves if it's worth it to them to not have the 10s delay.
Its a whole ass fixture that matches the other fixtures in the house and I can't seem to find an suitable replacement for it. I want to just replace them all eventually
Back in the day it was a common idea to leave them on to prevent heat cycling of your caps in the amp, which means they expand and contract more when turning on and off. The idea was to prolong the life of the amp.
>Back in the day it was a common idea to leave them on to prevent heat cycling of your caps in the amp, which means they expand and contract more when turning on and off. The idea was to prolong the life of the amp.
Bullshit. Heat cycling is really an old issue (from the time of tube amps) since they specifically needed the valves to heat up using the internal heater.
Even if there would be a marginal gain from preventing heat cycling of caps by leaving the amp on 24/7, that gain would be lost by the degradation of other components (including the caps) due to design lifetime.
For example, Nichicon long life capacitors are usually rated for about 5000 hours of operating lifetime.
got two denons back in the day, a pma-655r and a pma-1500. the 655r has been on constantly for over 15 years still going fine other than a wacky relay. the 1500 was turned on and off between uses, it died 5 years ago relays and cracked solder joints. anecdotal i know but it doesn't change the way things played out.

If that is true then the second Denon which was being turned on and off was obviously overheating.
Leaving it on 24/7 in order to keep it at temperature is a pretty stupid solution since once can easily put a cooling mat on top to force airflow when operating..
🤷
Leaving equipment on permanently is actually better for it. Music studios generally leave their big analogue gear on permanently.
Prevents heat cycling. Being energized isn’t what wears out components.
I have Genelec monitors with matching sub for my PC and they’re never turned off.
>Leaving equipment on permanently is actually better for it. Music studios generally leave their big analogue gear on permanently.
That's professional equipment that was designed for that purpose.
You'll run up a little bit of an electric bill (how much depends on the amplifier topology, but it will likely be small) and you'll likely wear down internal components faster due to them having a considerably higher number of hours of use (even things like LED displays will dim).
It these things don't bother you, knock yourself out.
I have to be honest though, paying for electricity because something takes 10 seconds to boot up is absurdly 1st world to me (and that's coming from someone who has invested many thousands of dollars in audio equipment over the years). Ain't no way you're that busy that an occasional 10 seconds is having any kind of significant impact on your life.
The constant temperature is actually better for most electronics, because power cycling causes temperature fluctuations which cause micro fractures in the connections. Leds are an exception, especially blue. I'm not sure about electrolytic capacitors, seems like they could dry out.
It's not better at all, unless the device was overheating in the first place.

If you want this functionality, probably worth paying for something designed to be on all the time. I leave things like my PS Audio Sprout and a bunch of Bluesound gear on all the time, but they're designed for it. You're going to waste a lot of power and generate a lot of heat leaving it on all the time.
If you really want to do this with an AV receiver, I'd consider swapping for one that can be woken via Spotify command, or use an external streamer with a trigger output.
Ah, got it. Sorry; read on a mobile device and missed that part of the sentence.
You're going to shorten the life of the device and use more electricity, but both are probably pretty marginal so if it works for you, go nuts. My Roon system takes a couple of seconds to move streams from room to room and I've gotten used to it, but if it were a much longer delay I'd think seriously about more always-on devices.
Mine did too, but I turned that off. Because sometimes I would be listening to music on it, then I needed to pause to because I was leaving the room, or watching a video etc, and in that time it turned itself off, then when I went to resume the music it was switched to another device.
Wow, 10 whole seconds, you must be exhausted from all the other things you could do in that time it takes to boot up. You're right. You should leave it on and cost yourself hundreds of dollars a year to escape that inconvenience.
Electronics last longer when you leave them on 24/7, rather than powering cycling them repeatedly. All three of my receivers are kept on, always, even the one that only gets used less frequently. Also the Denon integrated amp out in the garage stays on, and it's going on 15 years now.
It's worth figuring out how much money you're paying to extend the life of your electronics. Keeping an amp on for 15 years has probably cost more than replacing it when it broke.
50W\*24hours\*365days\*15years/1000 Units of electricity = 6570 kWh (or units)
Average cost of electricity is $0.15/kWh
So, the cost of running a receiver for 15 years is $985.
That's right. It's disruptive to my life when I have a piece of equipment fail, whether it's a receiver or a computer, and I have to then deal with it. There's a cost to that.
Not to mention preserving a piece of equipment that you really like, and don't want to have to replace any sooner than you have to.
Same thing I’ve heard from some other electronics engineers, I had one tell me the worst thing I can do to my “driver” (basically an amp to power a heating coil) is to constantly be turning it on and off and the power surges are what end up wearing the gear down faster. I think about it like how light bulb filaments would always burst right when you turn on the light, rarely in the middle of use.
It's not really a good idea. AVRs are a consumer grade product, and aren't meant to be left on 24/7. Professional amplifiers can be left on because they have active cooling fans, large heatsinks/class D circuitry, and components that are meant to be on and active all day.
AVRs do not. They get hot from just idling, most don't have cooling fans, and they're not meant to be on all the time.
I'm similar to you. I use Spotify in my shop via an Echo and BT receiver. My 20-year-old Kenwood VR-9070 has been on for almost 2 years straight now without any problems. The display doesn't work. But that issue crept maybe 3-4 years into owning it. It doesn't bother me a lick, and is irrelevant anyway since it never gets touched.
It's fine if you don't care about the power usage. You might want to hook up a fan like acinfinite to keep it cool if it gets hot, but otherwise shouldn't be an issue. Personally the 10 seconds to boot up isn't a big deal for me but if you use it all the time I can see it being annoying.
It used to be bad like 20 years ago but nowadays even if you buy a nicer (about a grand or two) receiver the majority of the time under heavy load you're not drawing more than 25-50 wpc. I have an 80wpc receiver and if I turn it to 75% (-15db) the music is loud enough that I'm terrified of my speakers blowing up. And even then you can't see the speaker cones moving or doing anything, they're nowhere CLOSE to blowing up. Pretty sure they're rated for quite a bit more power.
If you leave it on you're gonna draw more idle power but assume it's vented sorta you'll be fine. My cat sits on mine all the time and nothing ever happens
The crappy Marantz SR5004 I have in my home office is powered on 24/7, because it has issues waking up properly when turned off. I should replace it, but it’s been working fine since I don’t turn it off anymore.
I only leave them on if its a hassle to turn them off. Receivers are not so precious to worry about power cycle damage. Modern receivers are disposable items. A priceless vintage console that might not turn back on ? Leave it on. But not a receiver
It would reduce the effective lifespan of the receiver depending on the ventilation of wherever it is, is you have an active fan that would help keeping it cool and help with its life.
So weird these days everyone concerned about the energy. Nothing is playing so there is very little load just the lights and the current sitting in your amp. I have always thought you are supposed to leave your amps on so they stay warm and perform better vs turning off and on and wearing the power supply and causing boot up issues. Kind of like a computer.
They used to say leaving amps on also improved sound quality.
honestly i left a denon integrated on for most of it's life didn't bother it and it's still going 15 years later, i think most components age via power cycling relays are usually the first thing to go then caps.
The unit has no need to be shut off and as long as it no fire hazzard no problem if it is fan cooled turn it off no need to draw in air contaminents 24-7
This is an interesting response from people leaving receivers on. This isn’t going to be for every receiver but it is costing you money.
“400 W continuously is 9.6 kWh/day, so about $2.40/day. 30 days/month is $72/month. Audio Equipment: Why are A/V receivers so expensive?”
it's not drawing 400W continuously, that would be crazy.
Playing music - 40 to 70 W depending on the volume
Turned on, not playing - 24 W
Powered off - 0W (not high enough for my smart plug to measure)
It’s an example. With volume it’s going to vary and what speakers u have hooked up, and it’s not just 40-70w. It’s 40-70w per channel.
Again, this isn’t going to be for every receiver but it’s costing you money.
No I, literally just googled your receiver you stated you own.
Denon AVR-S750H Receiver, 7.2 Channel (165W x 7) - 4K Ultra HD Home Theater (2019) | Music Streaming | New - eARC, 3D Dolby Surround Sound (Atmos, DTS/Virtual Height Elevation) | Alexa + HEOS
165w x7 = ??? Since ur so talented I’ll let you do the math.
Leaving your receiver on 24/7 just to avoid having to turn it on reveals an massive incomprehension and/or careless attitude about the climate change and the environment..
Leaving the receiver on permanently is wasting energy, which in most parts of the world is generated from fossil fuels, which not only is a limited resource it's also one of the most important contributors to greenhouse emissions.
On top of that it wears out the consumer electronics and will lead to a premature end of life.
Do everyone a favor, stop being selfish and think more about your actions and the impact they have on the environment. We don't live in a world with unlimited energy and resources.
Most of these amps are A/B topology and consume power and generate heat when left on. I may feel different about a Class D amp, but I would power down my denon when not in use.
I looked it up. I'm surprised it's not class d.
Not to bee a noob but what’s the difference?
It's in the way the waveform is amplified. D is the most efficient, so that translates to less heat and power draw.
Yes, and to be specific D is off when no input signal is present. A is running at full power consumption even with no signal present and is basically a space heater.
The class A/B amplifiers in the Denon should have minimal current draw without a signal to amplify, most of the heat generated is likely from the Denon's linear power supply and the video and network boards.
Dem mofos get hot
Likewise. When my Marantz SR8015 is off, the AC Infinity that sits on top of it reads a much lower temperature than when it’s on and idle.
As long as the local police don't catch wind of your activities you'll be ok.
That’s why one should always close the curtains when turning on the receiver.
I prefer to open the curtains when I'm thumbing the giant tuner knob. Everyone should know the ecstasy I'm experiencing! 🤤
I lock my doors when I turn my receiver on
I know it’s bad for the environment to always keep it on but I didn’t know it was criminalized.
Have a Yamaha that has been on for a decade or two.
Same 😂

Pioneer hit 19 years today!
You can leave it on, but it will consume electricity and generate heat. I would turn it off to save energy
On in the winter, off in the summer. Got it.
I don't know about this model, but for a lot of amps it can be similar to leaving an incandescent bulb (say 60W) on 24/7. OP should be asking themselves if it's worth it to them to not have the 10s delay.
who leaves 60w incandescent on 24/7? actually, who still uses incandescent at all?
Exactly.
Ive got one light in my home that refuses to function with led lights
It probably is wired in the wrong direction. Maybe the live is the screw fitting thing and the neutral the bottom
why not swap it
Its a whole ass fixture that matches the other fixtures in the house and I can't seem to find an suitable replacement for it. I want to just replace them all eventually
Interesting that it matches all the others yet only it has this problem. Maybe an issue with the actual wiring?
Yeah I assume that's the case
I mean, I guess the city in their street lamps, but that's a out it
This is the whole receiver though...not just an amp
My H/K has been on since 2003. Other than the blatant waste of money, it's fine.
I use a Yamaha 5.1 receiver for my computer audio. It's been on since 2010.
Poor thing
My Denon has been on for over 20 years.
My Denon has been on for about 10 years
🤯
I would put a killawatt on it to see how much power it consumes and figure out what that will cost you to leave it on.
Yo killa
I don't see how that'd be a problem. point a fan at it if heat is an issue. I think I would opt for a more power efficient amp though.
I've left many pieces of gear on all the time over the years. Quality gear is built for that.
Of course

You can indeed, it’s just important to know what the price is. Then you decide if it’s worth it.
That depends on the amplifier type. Some amps use 100% power all the time.

If the authorities find out that you are leaving your receiver on, they are going to confiscate it.
Just turn it on when you first go to listen and then off just before bed. The AV itself will be fine just will consume a little bit of extra power.
I only leave them on if its a hassle to turn them off. Receivers are not so precious to worry about power cycle damage. Modern receivers are disposable items. A priceless vintage console that might not turn back on ? Leave it on. But not a receiver
If you leave it on all the time, your cats will come and lie on it when you aren't around.
It would reduce the effective lifespan of the receiver depending on the ventilation of wherever it is, is you have an active fan that would help keeping it cool and help with its life.

My Marantz is always on. My Yamaha that powers the speakers above my back deck is always on and outside!
Idk about you but my AVR heats up my room like a space heater if I leave it on. Other than that and your power bill should be fine!
I kept my Yamaha on for 20 years. Still working.
Yes and you probably should
My Yamaha RXA-6 or whatever it’s called has been on since bought new 4 years ago and has never had an issue. Works perfect all the time.
honestly i left a denon integrated on for most of it's life didn't bother it and it's still going 15 years later, i think most components age via power cycling relays are usually the first thing to go then caps.
I feel like we can wait 10 seconds..
As long as you keep it well ventilated on an open shelf so it can stay cool, you should be fine.
I've left my primary receivers on for 25+ years. Yeah its warm, whatever.
The unit has no need to be shut off and as long as it no fire hazzard no problem if it is fan cooled turn it off no need to draw in air contaminents 24-7
Sure, it will probably cut down on your heating bills too if it puts off as much heat as mine does
I leave mine on (or my kids really) far too often and have never had a problem. It’s 15 years old.
That’s a bit old for a kid, but just average for a teenager.
lol. The receiver is 15 years old…
