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?

Sounds great to me also look at Pass 350.8 plenty of power not overpriced like CH.CH is great as well its your move.

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.

i don't know the amp, but based on the power rating and the andra's specs as a driven load, it should work fine -- unless you play the music very very loud

but really no way to know for sure for yourself until you try it!

Thanks Kijanki, that’s what I was looking for.   The VAC preamp has a lot of gain (almost too much), which is why I can’t go past 9-10 o’clock on most recordings.
