hum with 2wq filters/ general hum help needed


my system is vandersteen 3a sigs, stereo 2wq's, first sound presence deluxe mkII, BAT VK 200, ayre cx-7, musical fidelity trivista sacd, and modwright 999es. i have used wx-2, old version m5, and new version m5. every time i hook up the filters, hum starts. with the trivista hooked up there is no hum, remove the tri-vista and the hum returns. remove the filter and the hum goes away. hum only occurs when the amp is on. i'm also using adapters from the single ended pre to the balanced amp. filters are single ended. any thoughts or suggestions? also wondered what star grounding is and is it safe?
