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.

Definitely maybe. Speaking as one without the technical experience to even provide you with an opinion...at all costs audition in your system compared to your current component.

That said, I heard the Sanders Magtech amplifier in a somewhat familiar system, not mine, compared to the owners Bryston 7B's. Similar power but the difference in presentation was very noticeable.

Level 4 skier. Haven't skied in six years. New boots and skies last season, WOW, talk about gear related improvements!
