Hello Everyone:

I never did try connecting the speakers directly to the wall sockets. I only connected through a regular extension cord with 4 sockets, then through the Monster 3500, then through the Furman IT Ref 15.

Unfortunately, since I do not have one of the D6000s, or the boards for my dSP6000c, I cannot test them by going directly to the wall.

My electrical panel is in my basement almost directly under the room in question. The length of the wiring to the wall socket is estimated at 10-20 feet at most.

After reading all the great feedback and ideas on this thread, I wish I had kept the speakers home to experiment. I would now like to take them to a friends home, place them in a smaller room, connect them directly to the wall and see what they do.

If they do the same thing, this would eliminate the conditioner, room size and openness, and electrical issues---thereby reducing the issue to hardware of some kind.

When the Meridian Area Sales Manager came to my home, he did happen to be in the Chicago area. The 2 techs worked with the local dealer.

I will phone the tech in Atlanta on Monday and see if he thinks sending down both D6000s (everything) is the best avenue. Ha may not know the answer until he looks at what he has or is still to receive. It has been two weeks since the Dealer and company have left my home, and I have heard Zero from anyone except the Atlanta tech sending me the shipping box for my DSP6000c boards like he promised.

So, unfortunately, at this rate, it may take 1-4 months to find out what is going on?? Now again, I go back to my commentary on customer service?? I am not asking for anything free, and am quite willing to pay a premium to get to the bottom of this issue.

Ncpl---thanks for the names at Meridian UK---this will come in handy if Atlanta sends me there.
