Any way to know amplifier idle power consumption? (wattage at wall)

[digitalfrost]

Both my class AB amplifiers that I measrued used 50w idle. One was from the 1980s the other I bought in the 2000s.

The upcoming Hypex Nilai500 module will probably be close to this, too.

More meaningless Hype from Hypex. I guess not unexpected.

"We are extremely excited to announce this completely new Nilai Class D technology and a completely new amplifier module, the Nilai500DIY, for the DIY community. We have taken our exciting control-loop topology to a whole new level resulting in an immense performance upgrade compared to Ncore. The overall performance has increased by not less than 10 times!", says Hypex.

10 times the power?
10 times the dynamic range?
10 times faster?
10 times the bandwidth?
10 times less THD?
10 times less power consumption?
10 times cheaper?
10 times smaller?

I think not. Maybe one metric, if we are lucky.

Just buy a good quality plug in-in-line power meter. Not one with wifi, bluetooth and sophisticated calculations of tariffs and cost- that's no good for what you want in this instance. You want something you can carry with you and check a product before buying?

I can't really see myself going in the local hi-fi shop, an eccentric to the outside world, but at least begrudgingly accepted inside, then producing a power meter and asking if I can rummage around the back of a few amplifiers and pull out a few shelves to see what amplifier idle wattage is.

I can just imagine the looks now and I think that degree of ostracization would be too much to bear, even for me.

How is that relevant to my point or the topic of this thread? They state "With idle losses of only 2,2W compared to 4,5W for the existing NC400 module, Hypex also managed to get the heat dissipation much lower.". That is the only relevant information here.

It probably corelates with the power?
my PA speakers are rated 500W and manual says: 230mA@100Vac / 180mA@127Vac / 120mA@220Vac

I don't think so.
Mine has 30 watt idle and the power per IcePower is 1200 W / 4 Ohm per channel ≤ 1 % THD+N, 1 kHz.

Power vs mains

Edit:charts.

Hi, I have recently relocated from Singapore to Canada. All the Hifi Equipment I used in Singapore was 230 VAC 50Hz. Based on my limited understanding, all this equipment was ok with 50 to 60 Hz frequency, and all I need is a suitable Step-up Transformer to step up 120 VAC in Canada to 230VAC. Kindly let me know if you guys have experience in using such equipment.

Look at the back of your gear to see if it has a universal supply. if it does, it will say that it works from 110 to say 250. Otherwise yes, you need to get an appropriately sized step up transformer or AC power supply.

And no, the frequency doesn't matter unless you have a turntable or reel to reel tape deck in which case, it may or may not matter

I own a bunch of Hifi Components rated 230VAC 50Hz, Integrated Amplifier (298W) / CD - Streamer (150W) / Phono stage (65W) / Power supply Phono (250W) / Power Supply TT (100W). Now I am Canada 120 VAC 60 Hz. I plan to use a (One unit) Krieger ULT1700 1700W Step up Transformer to power them all. Kindly assist in sharing if I am safer with the step-up Transformer selection.
Note: The Watts, as mentioned above, are the statements on the manufacturer brochures.

Hi Team, any feedback on this one? Your help is greatly appreciated.
