    Does the problem only manifest itself when one particular source is selected? or at all times?

    Maybe it would be a good idea to try switching on the amp,waiting a few minutes then switching on the C.D. player (or vice versa).
    Also, does the hum level vary with volume control setting? If the C.D. player is at fault, I would expect it to.

    Today,I did an experience with another cd player that use RCA´s,unllike my Naim that use DIN and so far the huummm is not so loud,but it still appears for 1 or two minutes but now much more lower!But now it apperas on speakers,not trough the speakers,like some nasty frequence.
    What you guy´s suggest?Is it normal,I read on some foruns that many have huummm issues related with amp transformers!

    The amp is going back to Denmark!
    BTW,is it possible to fix the problem without hearing the nasty noise?
    I mean ,it just happens sometimes,I´m affraid that they have to try several times turn on and off the amp until be able to hear it!

    If you've given them the symptoms they'll be able to sort it out and will probably have a VERY good idea of what to look at first.
