But that’s just a poor implementation in the audio system.

Auto-off has been common in active studio monitors (the powered speakers in recording studios) for ages and ages, and works fine. I have some Jamo active speakers from the 90s which wake from standby within a fraction of a second.

Part of it is how long the speakers decide to wait between applying power to the power amp and connecting it to the speakers via relays (or enabling the output on a class D amp chip).

Another source of delays isn’t the speakers, but the sources. Especially with digital connections, where there are multiple data formats, and the decoder has to wait long enough to actually identify the format in use. (And some decoders, like my Denon home theater received, audibly pop when changing formats).

HDCP (the encryption on HDMI) contributes to delays on HDMI. The handshaking adds some delay.

So in reality, I doubt the EU rules have much to do with it. Many factors have been conspiring for years and years to slow down picture and audio connection setup, each alone adding a negligible amount, but in total an uncomfortable delay.

That's a good point, as regards speaker systems.  (I'm guessing, since I haven't opened up the speakers, or seen a schematic for them) I imagine, there are some hefty capacitors in the speakers/amplifiers, which were perhaps designed BEFORE the EU regulations existed or came to be valid.
So, the possibly old design couldn't cope with switching on very quickly.  But there are a number of other possible reasons for the delay, which as you said, can be largely designed out of equipment, usually.

But in the future, they can sort problems like that out (I think the speakers in question, first came out around 2014), then everyone can be happy.

Standby power consumption, is probably a good example, of where the normal consumer.  Is probably completely clueless, as regards that concept, and may have little idea on what various items, standby power consumption might be.

For the speakers, just get pro speakers and a pro audio interface. I use Yamaha HS7s and an Audient id44 and it works reliably.

Thanks for the suggestion.  It looks good.

Looking at a typical 8k TV review/recommendation website, such as here:

https://parker-marker.com/blogs/electronics/television-review/is-an-8k-tv-worth-it-heres-our-expert-answer/

They seem to be around 65" to 85" (inches).  At 85", there begins to be a significant argument, that the extra pixel density, is needed, to stop the screen appearing pixelated and/or worse due to lack of pixels.  Depending on viewing distances and quality of TV picture, the buyers are looking for.

So, on the one hand it makes me understand the need for 8k TVs, if people are going to buy TVs that size.  But also makes me think the EU, maybe has a point with the legislation, because as TVs become so big, and less efficient (because of going to 8k).  The electricity consumed, is going to be a lot more significant.  I.e. considerably more power will be used, compared to a much more modestly sized TV, of around 4k.
