100 watts enough?

Hi all.  I'm contemplating purchasing a CH Precision A1 and I don't know if it will drive my speakers adequately.  I have EgglestonWorks Andra III speakers which are 88db efficient (impedance 8 ohms nominal, 6 ohms minimal).  I have a 30x20ft  room and I sit about 14ft from the speakers.  I live in a condo and have almost nothing between me and my neighbor so I don't ever crank up the volume.  I use a VAC Renaissance preamp that I almost never crank past 9 o'clock.  The Andra III is a speaker that likes lots of power to open up.  So what do you think?

These massive 25 watt only into 8ohm ML2 monoblocks will drive a pair of Wilson Alexia’s (hardest speaker known to drive in the bass 0.9ohm ) magnificently to a certain loudness because they can do big current.

They almost double their wattage for each halving of impedance all the way down to 1ohm-200W!!!

As you can see wattage is not everything!

Cheers George

No one has posted the combined impedance/-phase graph on these, so here it is. Even the EPDR loading will be easy.

As you can see easy load, even tubes from the 4ohm tap will sound great into them.
