Just got my new ASL Hurricanes....and.......

.....I am still taking time for them to break in. I have been told that they take 10-15 hours before they start to begin to sound good. Right now I'd like to hold off on my initial comments till that time, however I have some questions to you all (especially the tech folks-I am NOT a TECH person AT ALL).
First let me say that the Hurricanes are replacing an ARC VT 100 MKll 100 watt tube amp (a sweetheart). My speakers are Infinity RS 1-B's. They are a 4 column system with an active crossover (servo) for the woofer columns. The woofers are being powered by (for now) a Perreaux 2150B @ 400 watt into 4 ohms.
OK...got it?

First question. ...(and I think I know the answer)...I am getting a 60 htz hum from my mid/tweeter columns that are being powered by the Hurricanes. The power cords are plugged into a Richard Grey 400 power unit. The power cord looks cheep but do you think I will need cheater adaptor??
I am picking two up tomorrow ..... COMMENTS

Second question....(and again I think I know the answer)..I need to boost the bass output on the crossover now...I guess 100 watts vs 200 watts makes a big difference? However, I am upgrading my bass amp from 400 watts to (I think-help Sean) 600 watts soon when i pick up the Perreaux 3150pbm. Will that make a difference....I assume it will??
COMMENTS.

Again, thanks for your time and help!
