Totally true.  I tried to tell someone that they would do better to get a 
higher gain antenna than a 1.76 dB increase in power.  Of course, if you 
have a TH7DXX or some other super array of yagis, then maybe increasing 
antenna gain isn't practical.  So if you can afford the HUGE antennas, 
then buy the big amp.  However, if you have just a dipole or a vertical, 
you are much better off investing a few hundred bucks in a really good 
antenna and purchase a 1 KW amp for less than a 1.5KW.  a six dB 
improvement in TX AND RX gain is far better than just a 1.75 dB 
improvement in TX power.

What do they say about guys with big power boats or sportscars???  
Something Freudian comes to mind.  Maybe the same is true with HF amps!  
To quote Tim Allen, "Errr..Errr!"

But 1.75 dB might make a difference in some rare instances.  Those are 
pretty rare.  If it makes such a tremendous difference all the time, then 
why am I able to work rare DX with 100 Watts?  I guess we all like to 
"push the limits" and use the maximum of whatever is available.

True true...Psychology is over on the Doctor Laura reflector! :-)

Good points though......
