Hi, bhakti-rider,
My situation is not quite the same as yours but it is similar...
I have the Dynaudio Contour S1.4 speakers and they, too, need plenty of reserve power. I use a combination of a PrimaLuna Prologue Premium preamp and a NAD M22 power amp. I get the wonderful richness and bloom of the Prologue's tubes along with 250W continuous/640W peak power into 4ohms of the M22's class D amp section. When I upgraded to this pairing, in addition to the Prologue's signature sound, I immediately noticed the improved control and definition of bass notes along with an overall improvement in dynamic contrasts and definition offered by the M22 power amp. The S1.4
I'm not trying to recommend this pairing (and don't want to start a discussion of class D power amps) but offer it as an example of how the Dynaudio speakers do well with plenty of reserve power.
Regards,
Tom
