Hi All
I added a Lyngdorf SAD-2400 to my Arcam AVR390 as my new DIY speakers need a good kicking and boy does the Lyngdorf do that!
I was, until adding the Lyngdorf, using my old Pioneer receiver as a power amp with no problems at all, in fact, it worked surprisingly well.
However, I now have an earth-loop hum coming from the Lyngdorf. Only thing I've tried so far is changing from phono-phono to phono to XLR but no difference.
I suspect the problem comes from the lyngdorf having 3 pins connected (as in it's earthed via the mains lead) and the Arcam and Pioneer only have two pins connected. I don't really understand why they are not earthed, I'm sure there's good reason?
What do I do here? Do I make a power cable without the earth for the Lyngdorf or do I somehow connect the chassis of the Arcam to the chassis of the Lyngdorf?
