How Much Difference Does a More Powerful Amp Make?

When would you notice a real difference in sound quality with a more powerful amplifier?

I have a Simaudio W-7 driving Dynaudio Sapphires, and at some point, I may upgrade to Sonus Faber Amati Futuras.

My W-7 is 150 watts at 8 Ohms, and Simaudio makes the W-8 at 250 W at 8 Ohms. Would I notice any difference if I moved to the more powerful amp in a medium-sized room (14' x 22' x 8')?

The Sapphires are 89 db efficient, the Futuras are around 90 Db, but I've read that with most speakers, the more power the better.

I have a similar consideration. Recently I added a second amp bi wired vertically into my system. Aragon 8002 125 watts. The second amp really helped in detail and yielded a more relaxed sound.
Now I have a chance to get a pair of Aragon Palladiums 400wpc
to drive my Snell CV's. I am thinking this too should make a nice improvement.
Will this extra power yields even better results? I will have a chance to test drive these puppies and they were top of the line @ $5 K. Hmmmmmmmm...
