I think power is a bit like a car engine yes a 1 litre can do 70mph but ask it suddenly to go to 100mph it will really struggle to do it but a 3 litre engine would take it in its stride.
There was an article last year about making all amps sound the same, all the guy did to make a 250w amp sound like a 60w was reduce the power it changed the sound.
Unless the car with the smaller engine (power) had bigger wheels/longer gearing (senstive speakers) it would go faster

Your attempt at an analogy would actually make the car slower to respond and its low power would quite likely make it unable to make use of the taller gearing and increased rolling radius of the wheels.

At a recent music festival I was sitting 5 to 7 metres from the bands. A 10 piece string ensemble peaked at 82 dbs. A 90 person big band with amplification of some instruments peaked at 108dbs. An unamplified solo drumkit peaked at 99dbs.
OOI do you get any funny looks at a music festival when you're taking measurements with an SPL meter?
I kept it discrete, not wanting to put the young musicians off, as the sound meter does look like a recording microphone. IE kept it on my lap partially hidden by a jumper so that the performers couldn't see it. As for people in the audience I have no idea if I got funny looks from them as I was concentrating on the captivating performances of the musicians.
Well acceleration aside, you could still get just as fast, it would just take a lot longer.
In terms of how loud you want to go:
Low power amp with senstive speakers = High power amp with in-senstive speakers.
Its a trade off between size, bass depth and sensitivity.
Power is not everything.... IME / IMO etc etc
So the general concensus so far is that you don't need much more than about 30W? Good luck with that I say.
This may be suitable for dynamically compressed recordings, but not with wider dynamic ranges. It's the transient swings that are the problem.
A quick web search will tell you all you need to know about clipping.
Overdose, that's why I asked you how many dbs at 1 meter your speakers are putting out on the loudest peaks at the loudest volumes you ever listen at? And how many dbs is that at your listening position?
It's impossible for me or anyone else to say how many watts someone needs - even on the most dynamic of recordings - without knowing their speaker efficiency, the maximum peak db level they listen at and how far they sit from their speakers.
Funny that looking at max speeds the more powerful engines seem to be higher but if a 1l can go the same speed as 3l but takes longer to get there why do most have a max. speed of around 100mph but 3l ones can do 140mph?
If they were in space I might agree with you.
It was not designed as a literal comparison between Hifi Speakers/Amps and Cars. Thats completley different arguements.
You can only gauge a rough comparison like in a car, how much power/how fast it goes is not an indication of how enjoyable it is to drive, much the same way how loud a hifi goes is not an indication of how good it actually sounds.
Anyway, thats all I will add, its now well off topic
It not so much about watts which is a pretty poor measurement anyway. It is really about how it sounds at the level you want to listen at. What speakers do you have, what room size, what musical source?
The extra headroom inherent in more powerful amplifiers is to enable transient swings to be dealt with effectively. Like I said, use a 30W amp if it suits and you feel comfortable, but a more powerful amplifier is always a safer bet. If you want to draw analogies, it's not about outright speed, but acceleration and braking, both of which are done with less effort with larger engines in a vehicle.
Why do many amps sound best when the volume control is around 10-11 oclock? That is only a few watts if that. As I said the Rega did not sound good at 12 oclock and I did not push it any further.
Your comment has almost slipped by unnoticed....and unless one has personally experienced a well designed 30W SS Class A, it's difficult to grasp just how powerful they can be. Not all 30W are created equal.

Haha, you got the wrong person I was asking the OP.
Oops my bad
