I'm currently on my second set of the above speakers after having the first
lot returned due to a hissing sound.

The second lot are much much better, but the hissing is still there and
seems excessively loud for an alleged THX setup.  It's a middle pitched
hiss, quite light on bass but noticeable at a couple of metres range.
Interestingly the noise level is independent of the volume settings and is
even there when I mute the system.

It's not coming from the inputs as it's still there even when I unplug all
the inputs and it's not a specific speaker as all of them produce the sound
when plugged in individually.

The sub doesn't produce any noise at all, but from the above investigations
it seems to be clear that the amp inside it is producing the noise.

The oddest thing is that every so often, for no predictable reason, the
hissing dissappears entirely only to come back a few minutes later.

I'm quite reticent to send them back again as it's quite a chore packing up
50 odd kilos of speaker (slight exaggeration) and shipping them back to
creative.

Has anyone any similar experience or suggestions?


Thanks in advance!
