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.

Given your speakers are quite efficient, I doubt you'd notice any difference at all. Yes, more is always better, but 150 is already more.
going from 150 to 250 isn't such a big a power boost as it would seem....in sand amps, high current designs are most powerful...i.e. doubling in power when going from 8 to 4 ohms.
Larry - Sand Amps ? :-) what does that make the other variant "Lack of Air Amps" Made me chuckle though.
