In my experience, a more powerful amp does not necessarily translate into better sound. I had Dynaudio C4's powered by a Plinius SA-102 (125 WPC), then thought I'd get more out of them moving to Simaudio W-6 monoblocks (425 WPC). Ended up being the wrong move and I sold the W-6's three days later. IMO, it's often the quality of the power that counts... not the number of watts. Based upon my experience with Simaudio & Dynaudio, I suggest you try something other than Simaudio with the Dyn's... maybe a higher powered tube amp from McIntosh (MC275), VAC or Conrad Johnson... or if you must stick with solid state, try the Plinius SA-102 class A amp, or a class A amp from Pass or Clayton.
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.
