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?

Stereophile lists them at 87dB and tested them with a Krell FPB 600 and VTL 750 monoblocks. Big amps. Considering you do not crank them, 100 watts might be okay. It's a lot of money to spend for a compromised—sorry, restricted—space where they may never get the chance to sing.

This is how you will get away with it. Those are some wonderful speakers. One of the very few I have heard that I really liked. Of course I never would consider them due to their extreme low sensitivity. But if you keep to low to moderate volume you should be fine. Better than fine. Been a long time since I heard them, and it was an earlier version than yours, but did they ever make a positive impression! Only other speakers ever came close were Avalon, don't recall which ones but they had the magic, like yours.

88dB - 12dB (4m distance) +3dB (room reflections) +3dB (two speakers) = 82dB@1W = 92dB@10W = 102dB@100W

I think you’ll be sorry. I’ve tried 100, 150, 200 watts, and it took a Pass X250 to wake my Aerial Acoustics 7B’s. Sure the other amps could drive them but I had to crank it to get them to sing and then I felt the amps were still struggling a little. With the bigger Pass, even at lower volumes which I tend to play most often, my system sounds great. With the other lower powered amps, listening to lower volume wasn’t at all enjoyable. Would love to try a Pass X350.8 in my system.
