Hum coming through speakers via Bat 300X

I just purchased a used Bat 300X/se and a new pair of Thiel CS2.4se's for a second system. Set them up last night and have a pretty good hum coming through the speakers. As I turn the volume up with no source playing the hum gets louder. Another weird thing is that I have to turn the volume up a lot more when the CD is the source compared to the turntable. I have the Bat plugged into a PS Audio P5 Power Plant which has never created a hum before when I used it. Any thoughts on either issue. Thanks-------

volume descrepancy is normal simply because your phonostage/cart combo gives larger input voltage vs. your CDp.
one way you maybe having a ground loop and need to isolate ground by using cheater plug. another way if that won't help, i'd try to get in touch with VK and possibly with seller that might've been aware of the existing problem...
