Logitech Z-5500's producing a really annoying popping sound

[DarkShadow]

As above, it has now been occurring since I bought them, I always had the impression that it'd go away but now it has started producing ever so slightly more frustating popping noises.

It has also started producing a humming sound if the speakers are turned on.

There is no interference, as everything is well placed.

I know some people here had the same issues, how did you resolve it? I'v gotten to a point when my headaches just can't handle the random popping throughout the day on a daily basis.

Bumpty bump.

After a quick google, I had read up on other people having these issues and so on.

I have very high end surge protectors. I used 2 of these *Belkin Gold Surge Protectors*

So that eliminates the need for clean power supply. Has anyone contacted Logitech regarding this issue?

I do wonder how logitech speaker sets get THX certification when they pick up and amplify interference/LineNoise so easily :/

My sentiments too

I mailed Logitech and here's the reply I got:

Didn't expect much of a reply, they make it sound as if it's a new issue.
