Idle Power — Post your measurements here!

[AudioHTIT]

I decided to move the Idle Power measurements here so they would be more visible and encourage everyone to measure and post their amp(s) and other devices. As people add their measurements to this thread, I will update this post so all the data is in one place, I’ll also update manufacturers’ specs or reviews as we run across them. While we’ll highlight amps, measurements from other Audio/HT gear is welcome too. I really want to focus on measurements in this thread, but discussion and questions are also welcome -- as long as it relates to idle power and/or measurements. 

This thread also has some thoughts on the topic
emotivalounge.proboards.com/post/909550/thread

I’m really hoping we can fill out the Emotiva section below, to encourage everyone I’m putting place holders for all the amps so you can easily see what we have and don’t have. I’ll fill in more as time allows, and might need help with the older gear.

A Kill-a-Watt (KAW) meter is generally the easiest and least expensive way to measure, but if you have other methods you could tell us how you did it. I’m not ignoring efficiency, we just don’t have an easy way to measure it. It’s also been mentioned that you may be able to ‘check out’ a KAW at your local library.

If you’re unsure how to take the idle reading:
1) plug the amp or other device into the KAW
2) turn on the power without applying any signal (turn the volume all the way down)
3) Wait a few minutes for the device to stabilize, 5 -10 min for a tube amb
4) Take a Wattage reading on the KAW
5) For extra credit take a voltage and power factor reading at the same time
6) Post the Make, Model, and readings in this thread.

Edit: I have also started to use the ‘Eve Energy’ Smart Plug, which besides switching, measures power that can be read from an App, I’ll note when this is the data source.

With 14.5Kw of solar generating capacity on my roof I could not care less about standby or idle power consumption. But even if I was sucking 'trons from a coal plant down the street I would not care, and I still really and honestly do not understand why anyone else does either. But whatever floats your boat.

[kybourbon]

I like it. The more data the better.

Hi All,

I had taken some of these idle power draw measurements for a previous post somewhere here:

Emotiva XPA-5: 70.1 W
Emotiva UMC-1: 28.8 W
Emotiva XMC-1: 35.0 W
Emotiva Ultra Sub 12: 9.2 W
OPPO BDP-95: 30.4 W

Are you familiar with the phrase "TMI"? Trust me - there is such a thing as too much data...

I think you may not have understood the attempt at humor...perhaps I should have put a smiley face by it to make sure it came across as a joke. In case it wasn't clear..."TMI" refers to "too much information". Such as when someone reveals something that borders on creepy about themselves to a group and the group kind of looks at each other in awe and later says "TMI!" as they talk about what happened. (As in..."why did he/she tell us that!?")

You had said that more data was always better...this was my way of jokingly saying..."well...not always"

As for folks who want the power draw data - "more power to them!" (No pun intended...) I don't need it but if others do...fine.

No I got it.

But I also saw the other ridiculous thread with people arguing with other people because they (gasp!) had the nerve to inquire about the draw of an amplifier.

LOL! I didn't even look and thought that this was still that one! Completely missed this was a new one!

The whole reason I have a 2000 watt amplifier in my Home Theater system is so I can think 🤔 about other things....like what to have for breakfast 🥞 !

2000 watts, eh? Cooking some bacon on that, I hope...

You may not need it, but I’d love to know how your NCores fit in here!

Thanks Cory, I’m suspicious of the UMC-1, I remember an idle over 100W, maybe even over 200. It was very high for a processor, and it ran very hot. I even remember when the XMC-1 came out thinking that 35W was more like it should be. I didn’t measure though and sold my UMC a few years ago. Do you still have one you could measure again?

[vneal]

no offense
dont care

No worries.

Absolutely...I still have it. I will get a reading this weekend and post.

Just measured the UMC-1 again:

My only offense is that I asked for this thread to be about measurements, and the other thread could continue the discussion, which I think this qualifies for. Obviously you’re not the only one, as my request was ignored immediately.

[leonski]

I'm working on measures of my Parasound amps. I'll have 2 amps to compare, to see how 'consistent' they are.
Tomorrow is 'Tire Day' for the 'Lament and than BBQ of some bacon wrapped steaks. Sunday the 'free' day.
I wish I had a very short 3"/1meter 12 ga extension cord.

Ok, guess I had that one wrong, thanks Cory!

Not a problem.
