I am not a native English speaker. I wonder what ‘Quiescent Consumption‘ means exactly for my Nait XS3. It is always on, so when is it quiescent? Volume dial to 0? Volume muted? Sources turned off?
It’s the current drawn in a no-load state, switched on but doing nothing

OK, that’s clear. 16W for an XS3 will not make a dent in my bank account

Possibly not…. But the environment will pay.
That’s actually why I asked. I am trying to be environmentally friendly. 16W when the XS3 is idle is acceptable to me.

In the grand scheme of things, turning it off at the end of the day and switching it on before listening again won’t hurt it, it’ll just take a little time to settle and come on song, just put the kettle on at that point.
Do avoid turning it off and on again too quickly, if it is switched off for any reason, allow the capacitors to fully discharge over a few minutes at least to avoid any unneccessary stress on the components.
Following those sensible rules won’t impact its service interval in any meaningful way.
It’s why the latest products have an active standby mode for low power consumption when not in use but keeping essential circuits powered to avoid any startup settling.
The XS3 actually behaves differently, compared to the 5si, when turned on/off. The 5si would cause a loud ‘thump’. I did n’t like that too much, so I never turned it off. The XS3 starts with volume muted and switches mute off after a few seconds.
You can’t have it both ways though. You either have standby mode, where the amp is fully powered down, or you override this by using the ‘instant on’ setting which keeps the main power supply powered up for optimum performance without a warmup period. It can only do this by pulling power from the mains: officially that’s 26W for a 250 and 20W for a 332, for example.
Valid points, the different products in the ranges do have differing levels of power states also, you right though, it’s basically equivalent to on or off where the power amps and NAC are concerned!
How much difference there is between standby and being switched off at the mains is presumably negligable overall.
They would need to comply with the regs which say <0.5W so yes, it should be negligible.
Poi: the two main systems are powered down due to maintenance. Asgaard’s monitoring progs., courtesy of a certain unpopular American batteries manufacturer, have not shown a decline in consumption, despite system 3 getting a hammering , although never left on.
