Pondering REL and Dynaudio subwoofers.

I recently got a rel classic 99 subwoofer, which sounds excellent and matches perfectly with my dynaudio heritage specials.  A thing is it has a well documented issue of a hum when my class D  Orchard Audio Starkrimson Ultra is powered off (also use Freya+ F).  I'm trying various methods to resolve that,.  Another option is to return that sub and get a dynaudio sub. 6.  I'm finding many features of the sub 6 being very intriguing.  DSP and matching base mgt with my Heritage specials.  I don't have a typical listening room, So my acoustics are not the best.

I'd be curious to hear any opinions on either the classic 99 or Sub 6.

Sounds like a ground loop issue that won't be resolved with a different sub. Which devices have 2 prong and 3 prong? They might not agree with each other.

Try the Earthquake GLI-200 or ISO-200. If it makes the ground loop worse, run a ground line on your devices to the amp, or any other combination that might work.

I have Dynaudio speakers and REL subs.  no issues, but different amps.  How do you have them hooked up?  I had issues with hum some years back with different amps, and it was a matter of floating the yellow wire or grounding the yellow wire to a chassis of an amp... can't exactly remember!

it is a ground loop problem of sorts known to happen with class D amps. Rel support has confirmed that.  

Was interested if anyone has compared the dynaudio sub 6 to the REL.
