Need Help Systemdek and Grado Cart..Possible?

So I just bought a Systemdek IIX which has an unshielded AC motor. I want to use an unshielded Grado Reference Platinum cartridge with it. Does anyone have experience with taming the RFI from the motor?

I have never used Mu-Metal but I wonder if that will work...if so, how does one use it to shield a motor?

Or..

ERS cloth / ErsaMat... would using a sheet of ERS or an ErsaMat on the platter provide enough shielding to eliminate hum in my Grado cart?

Would anyone please share their experiences?

Wow, thanks guys, this is really encouraging.. I might be worried over nothing, whew! The turntable should arrive in a week or and I can't wait to see what I'm in for.

Thanks again!

I pulled the trigger with the Sonata. It hummed, of course.

It turns out that Audionote supplies a motor shield for their current-production version of the IIX. I bought one directly from Audionote ($36.00 maybe?) and installed it. It still hums, but the hum is extremely attenuated. I'm tempted to try the ERSAmat under the felt, but I'm having a hard time parting with the $70. :)
