(I posted this in the Receivers/Amp section as well, but I'm desperate for some answers, so I'm putting it in this forum as well...)

I just invested in a new setup, including:

Monitor Audio RX6 towers
Marantz SR-5006

I hooked it up around four days ago, and I already notice when I'm switching sources on my receiver (from Xbox to HD-DVD to Net/USB, for example), the speakers make a brief and faint popping sound.

Is there a way to get rid of this, and why is this occurring exactly? I am worried only because my last setup was killed by a bad receiver, and I hope I'm not headed down that same path already.

The fault lies in the receiver, and no, it should not do that. If the pops are not loud it may be just an annoyance, but I'd return it anyway.

And I might keep it. Slight pops - as Bill noted - should not be happening but won't hurt anything and if you are as tolerant as I am you'll keep the Marantz. Loud pops can kill speakers.

When all else fails - RTFM!

Sorry for basically asking again, the same question you just answered, but are you sure these small pops won't be hurting my speakers? They happen when changing sources, or if the receiver needs to refresh (sorry, don't know the correct lingo), so may end up hearing a few small pops a day...

I'd rather not return the SR5006, but I don't want anything to happen to my RX6 speakers, which I paid an arm and a leg for - speakers which were a tad over my budget wink.gif...

To damage the speakers they'd have to be very loud. But they should not occur at all, so the receiver is defective and could get worse.

Ok, I've boiled down the problem.

I have a Sharp LC-32D43U tv. It's a 32', 720p HDTV from around 6-7 years ago.

Whenever the TV switches sources (for example, shutting off an HD-DVD player, Xbox, etc), it makes a loud cracking sound. That's what I've been hearing with the popping sound.

Is anyone familiar with this kind of pop? Can it damage my speakers if I don't get this rectified?

Thanks!
