Help -- EAD PM1000 and REL Strata III experience?

When I turn off my amp, I get a loud hum, unless I turn down the volume, from the REL. My understanding is that the PM1000 has no grounding, due to its internally bridged design (dual differential?). I've contact EAD and my REL dealer, but no luck yet. Has anyone experienced this with my combination. I tried lifting the ground with a cheater plug, connect REL's grounding lead to the PM1000 chassis screw--still the hum. I have yet to contact Sumiko. It's my last option.

Thanks for any help.

Hi!
I never noticed any hum from my REL Storm because my PM1000 is always on. Now I tryed some different set up and I am getting this hum only in one case - if Rel low input not connected to my Ovation. Is your low unput connected to your preamp?
If not try it or at least ground the outer contact of low input.
Please let us know what is the result.
BTW what is your Rel set up (phase, volume, roll off)?
