Translating my earlier comments about "how loud is music?" into watts:
to make a satisfying reproduction of organ and choir, I have two way active speakers; each bass unit is driven by 100w amp. and the widebands by 180w amps.

These amps. will readily make a noise that sounds realistic in a 35 cu.m. room without turning them to maximum. Could be thought of as overkill, but power is not the only criterium for choosing to build one amp. rather than another.

I seem to recall in the early 70s that there were amplifiers with significantly more than 100wpc. As a matter of fact, several recievers by the mid 70s had more than that.

the output SPL depends on both the amplifier and the speaker.
Use a 100dB speaker with a 1W amplifier and the maximum SPL will be around 100dB.
Increase the amplifier power to 10W and the maximum SPL will be around 110dB.
go for 100W amplifier and you end up around 120dB
go to 1000W for 130dB

But use that same 1000W into a 80dB speaker and you are back to 110dB SPL

I think it depends on whether you care about being able to accurately reproduce transient peaks. If you can live with a bit of clipping on the odd occasion, especially if your amplifier clips gracefully, then I'd say you don't need more than 10W for many speakers.

Absolutely true.. But! where's the bragging rights in that
For some (?), Audio 'gear' is often more about Status than anything else.

Well there's bragging rights in any amp. For some, the lower the power the bigger the bragging rights - go figure

It is scientifically proven that under 2000 watts no real music reproduction is possible.
To suggest otherwise, suffers from severe loss of reality.

More than enough for my use.
Judging by your choice of font size, 500W to 1000W would be more appropriate for your use though. Maybe 2000W just to be safe.
