jmacari,
Where did you read that "Apogee specs state not to exceed 100W"?

According to their web site: Suggested amp power
50W (into 8 ohms) 100W (into 4 ohms)

I'm guessing that the your B&K is rated 150W into 8ohms.

Bottom line is, you won't damage your speakers with too much power only with too little. The B&K will work great with the Apogees.

I ordered a 990 yesterday. Good luck to both of us
