In my experience, and I'm sure there are folks on this list with much more
experience and perhaps more astute observations, I agree with your number of
around 500 watts. I use a Centurion amp (which I love), and usually run a
maximum of 500 watts, never more than about 700 watts. I've found that any
station I can hear will respond with around 500 watts, so more power would only
make me audible to stations I can't hear. The most common situation in which
more power would be useful is getting through a pile-up competing against very
high power stations. I've found that having some patience, waiting for the big
guns with > 1.5 KW to finish, and waiting for the band conditions to change
slightly, usually gets me through with my 500 watt maximum. When I ran 100
watts, fifteen to twenty percent of the stations I could hear didn't respond.
When I run barefoot at 200 watts, only the weakest stations don't respond. Of
course, it's usually the weakest stations that I most want to conta
ct.
I'm currently using a 102-ft doublet with reasonable results, but am planning
on putting up a Yagi soon. It will be interesting to see if there is a
difference in the maximum useful power with an antenna with some gain.

Serious question -- So... where does it stop ? If 200 watts makes a 100 watt
rig just a bit better, why would a 300 watt amp not make that 200 watt rig just
a bit better and find you even more DX ? And so on down the slippery slope to
megawatts, each little bit digging more DX out than the previous bit? How far
down the slippery slope do we go before diminishing returns cancels any
marginal value from marginal additional power? What circumstances and factors
would force a different answer for different operators? (Serious question - not
just making an argument. -- Personally, I find the maximum usable power is
about 450-500 watts... any more and I don't make more contacts that I do at
that level, but should this not differ depending on antenna type and
deployment, and other factors such as external noise levels, etc.??)

there are many stations I have heard but could not > hear me due to QRM or QRN.
