Hi Carl,

Yes, I saw the illustrations and they are very useful. Thank you. I also spoke to Rick at Audio Images yesterday afternoon and I now understand that a hardware modification to the comms card is also highly likely to be required before the ID40 card will work. I need to remove my card to check it. He also made a recommendation for a power amp to use (Parasound Zamp), which also includes auto on/ standby features, so will meet my needs nicely and am therefore likely use the speakers I have already bought.
