I would be more concerned about the nature of the gain provided by the Direct Stream DAC than the wattage of the amplifier. I would think one would want to drive an amp using 30- 70% range on volume control of the DS DAC. Other may chime in on my thinking on this.
I think that by considering 50-100wpc amplifiers one opens up far greater possibilities. That wattage would not be over-kill for your speakers.
