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?

@unsound,
Not petty. However given what we know,  kijankii’s calculations and Stereophile measurement/testing, why would one conclude "merely adequate "?

Kijankii's measurements: ...."...102 dB@100W" seems closer to adequate than far more than adequate, at least to me. And at the risk of redundancy; it is a rather large room. I'll hazard a guess that the neighbor leaves home on occasion.

@unsound I hear you. I’m just basing it the OP suggesting his listening levels are modest. "I don’t ever crank it up". OP hasn’t chimed in to say what exactly those listening levels are in db for a better understanding. Modest levels to me would be mid 60s to mid 70s db C-weighted. In which case he’d be using only small fractions of a single watt.  10 watts gets him 92 db SPL. Well an interesting topic nonetheless. @unsound I appreciate your thoughts.

the OP can leapfrog half of audiogon with purchase and use of a decent SPL meter…..
or better yet RTA w calibrated mic. I would say the CH is going to kick some A
@charles1dad 

thank you ! the guy who designed the Treo feels same way. To be fair the RM-9 amp also designed by a genius - Roger Modjeski - RIP.

Having said all that my reference system is 1.2 Kw a side….but it’s not a condo…

isnt it wonderful we all have choices

i would be more interested in playing a few key tracks…say for instance a hand clap on a Norah Jones cut….and LISTENING to see IF the amp clips….
