Update:

I sent the empeg, suitably padded and boxed for the rigors of its 300KM journey to Sydney, on Wednesday. No more progress in my testing before that. Now making do with CD player - I don't know how people can stand only having an hour's worth of music available!

Thanks to everyone that has helped out so far, and a big thanks to Rod for the electronic expertise!
