buzzzzzzzz

Please help, i have a rega rp3 turntable with an elys mm cart played through a stageline and naim amps.
I have upgraded the power supply on the rp3 to a rega tt psu and am hearing an annoying buzz through the speakers, this did not happen when using the power supply that came with the turntable.
What is wrong?

I had this and had to connect a ground wire from my tt psu ( undo a screw a put a wire behind the head) and connect it to the earth on the phono stage..
