Hey people (sorry been away).

Have got two solutions.  One is a transformer which breaks the earth in the audio line. Bascially its inline from the output of the laptop to the input of the amplifier.
(Had this custom made by an audio engineer).

The second is the fusion ground loop isolator from dse.

Have yet to test them both as I had planned earlier. Perhaps I can do it this weekend (amp is off site in another location). 

Cheers

I have tried a similar isolator to the fusion one for a similar problem when sending audio over some long RCA cables at home.

VERY sensitive to local magnetic fields - just being within 400mm of a AC plugpack made major hum on it. In the end I put it into a steel box (which cost about the same as the isolator) and it made a little difference.

I gave up and ran spdif instead ;)

I have just picked up a bluetooth headset adaptor off deal extreme to use with my phone and laptop on the stereo, perhaps something like that would be an option, since there is no electrical connection?

Hi,   yes bluetooth sounds like an option, however, I dont completley trust the frequency response performance yet!
