    Thank you for your replies. The results of my tests are not encouraging:

    I tried each PowerLink cable on its own and between the two PowerLink ports. I also used headphones through the minijack at the bottom.

    With headphones everything sounds normal. The high pitched tone remains and the digital chirp only seems to be in the left most PowerLink port.

    I should mention that this equipment came with me from Europe, so its all 220V running on step up voltage convertors. I’ve even tried these in different outlets and plugged them into noise suppressing surge protectors.

    It sounds like the 9000 needs to go back unless this is a common problem with 220V B&O equipment on voltage boosters?
