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.

Isn't that what the Pass "first watt" thing is all about? There are a hundred things that make up a great amp, and power is only one of them. I think 100 clean high gain watts per side is just about right for my rig and room, but I was at a friend's place recently and he had some little triode tube mini watt thing and it sounded amazing, although not very loud. Note that for live stuff I've always used VERY large wattage amps...350 watts minimum into each speaker or uncompressed things don't fare well.
