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?

Oh, I'd like to hear them, where do you live?

Happily, your speakers were designed to allow bi-wiring. I'm thinking you will be just fine now, and if you ever move, want/need more volume, you could simply add a second amp, also designed for biamp/bridging,

two = 200 wpc, OR, depending on your preamp/future crossover simply add a less costly separate amp dedicated to the woofers, keep this amp for the more important tweeters/midrange.

BI– Amplification / BI Wiring Due to the unique crossover configuration of our loudspeakers, advantages of biamping and bi-wiring are maximized. We supply the Andra III with two sets of binding posts to allow for bi-wiring or bi-amping. The top set of binding posts drive the tweeter and midrange, and the bottom binding posts drive the woofer section.
