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?

@arcticdeth,

you sound like the type of neighbor I would avoid at all costs. 
Hi @unsound,
I get your point about loud volume levels and certainly it is subjective amongst respective listeners and their perception of such. Given the OP’s stated condo listening limitations/situation I’m guessing (And could be wrong) that 92 db SPL would be pretty loud relatively speaking.

There is your problem. 
88 db ~~~IN~~ Efficient speakers, 91db+ = EFFicinet speakers, 
91db < = INefficinet speakers, 
Power = power, 
you only need 25 watts to drive a   wide band.

It is true the lower the gain on the linestage vol, the sweeter/cleaner the sound.
But who here listens at a whisper.
So 9oclock - 10oclock is ideal gain on vol. Over 10oclock you are adding to distortion, making 85db max on vol level. 90db, yuckkk, tahts too LOUD mouth.
I listen at 70db near field. If 70, most likely 60

I am using no more than say 15 watts of the Defy 7's 100 watts.
