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.

The point has already been made but here it is in a cute form.
If the first watt sounds bad why would you want several hundred more of them?
Quality is the key and the usual recognition that some speakers really do need high current amplification to sound best. Essentially I am just agreeing with most of the comments thus far.
