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?

I'm wondering if you are being over cautious regarding the volume. A little louder could be acceptable depending on the construction material used between you and your neighbor.

I'm in a similar situation (13x40ft) and I've found a good test is to check the volume at the distant end of the room.

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

I love lots of power, I have 4.7kW in my living room. But for your condo application, I think 100W/channel is fine. If your planning to move into a house or a bigger place then investing in more power might be useful.

By the time that amp-speaker combo clips, the neighbors will be complaining.  Either way, you will either suffer the result, or turn it down until the unpleasant noise is abated.

Pressurizing a large room with full range of the notes is more than just db at the listening chair.
