It may be more complicated than shielding. Think about the grounds first.
Is the power cord for the PS grounded through a three prong plug? Is the phono stage grounded with a three prong plug? Is the PS connected to the phono stage through a shielded cable and does the cable also run a positive and ground wire between them?
As you can see there are several routes for a ground loop. Ensure the power cables are plugged into the same outlet or power strip. Ensure that the RCA jack on the integrated is not grounded to the chassis, but at a ground buss with all the rest of the grounds in the amp. Try plugging and unplugging the interconnect to see if the noise is reduced.
If you do try shielding, you could try copper roof flashing available at the hardware store. Try grounding it to the chassis ground and disconnecting it from chassis ground.
