    I have a set of 2005.1 Kef eggs connected to a Denon 3802 amp. Recently the eggs have started to emit a high pitched tone which, although not loud, is noticeable whether playing a source or not. The tone only disappears when I disconnect the subwoofer but then I don't have any bass.

    I'm not sure if this is a problem with the amp or the subwoofer. Can anyone provide any advice?

    Unbelievable, mine have just started doing exactly the same thing!

    Get a high pitched buzz intermittently, may be something to do with temp. Once its there, (and it comes out of all speakers), the only way of getting rid of it is to unplug the sub! (Powering off the sub, leaves the buzzing coming through the speakers.

    Ive got the original Kef sub / sats running on a Denon 3802. Is this a fault with the sub or the amp?

    Did you get yours fixed?

    Guys

    I had the buzzing through the speakers with the kef eggs. There is no problem with the sub or amp, it is down to something called earth or ground loop.

    I have got the KHT2005.2 and 3803 combo and happened to me. The way I solved it was to connect a piece of bell-wire from the ground on the back of the amp to the sub using ring crimp on both ends, and hey presto the buzzing is gone

    Do a search on this forum for Kef Ben and he lists what you have to do. Buzzing was driving me nuts but all is well now

    I has a similar problem. I too thought it was the ground problem but then realised that it was unlikely as it just suddenly started.

    My problem turned out to be the sub. The amp in the sub had started to fail. Infact, KEF admitted to me that that particular amp has more than it's fair share of amp problems.

    And it may have gone again!!! I'm not too impressed with KEF just at the moment.

    Check the white noise setup and see the the sub crackles, a sure sign that it's knackered.

    Which sub are you using, Joe Joe? THe one from the 2005.1 or the 2005.2 series?
    Cheers,

    To be honest I don't remember the model. It was the first kef egg range that came out, KHT2001 rings a bell.

    If it's important, I could find out?

    No problem. If it was the first model of eggs that came out, that tells me enough.
    I'm looking into the eggs myself and I was just curious.
    Cheers.

    So the fault was with the sub and not the ground loop issue?
