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.

I had a hum challenge with my REL B-1 sub. I called sumiko and I ended up moving my REL cable away from my other power cords and I also connected the black wire (per sumiko's suggestion) to a screw on the chassis of my amp.

No more hum at all...

I love my REL now!
