Why not horns?

Almarg: Thank you so much. You've explained it so much more eloquently that I. Indeed, the operative word I've been neglecting is MAXIMUM. And you are correct, the primary differences are current capability and heat dissipation.
I didn't anticipate these distinctions to have made a difference in an Avantgaurd Trio but it did. Why? Who knows for sure? To which my guess was that the amp with higher maximum power capability (based on current) handled even small impedance variations with more grace.

Thanks again for your input.

Almarg...... upon consideration I'm convinced you are correct.

All three of my examples have listed specs of 26dB gain. This equates to 400W, correct? (under ideal circumstances)
Yet the other specs are listed as 150W and 300W. The maximum wattage is not specified for paralleling the largest amp (VK-600m) So we can probably assume that it tops out at 400W maximum (still 26dB gain) with overkill ability on the current side.
All they are doing is adding more power supply and more heat dissipation.

Thanks again for your contribution. This probably wasn't the best example to illustrate my original point. ugh! haha.

Unsound is right.

Don't be a horn Nazi! Sharing of different views (that's all they are) by all including those who loathe horns is part of the learning experience. Just stick to the facts and I'm sure that horns will find some new devotees which is the best that can be hoped for realistically with any technology or approach discussed on this site.

"Horn Nazis"? Well, even the Nazis did some things well (roads for example) but that doesn't justify their other deeds. As I have said, horns do Dixieland jazz superbly, but I can't listen to Dixieland all the time.

I'm glad I gave up my audiophile card long ago, because thats when music became fun again. My Apogee dipole panel speakers are fun to listen to, and so are my horns (Klipsch).

My Bose 901's out in the garage are also fun....and so are my big old ugly VMPS Supertower/R's.

When I was an audiophile, I rarely found music or speakers that were fun, and once the fun was gone......so was I.

After around 5 years I came back for another try, and with a new goal......."Don't worry, be Happy"....and have fun!
