Don't worry about it. If it helps you in any way, I'm glad. Hopefully you can work something out; Craigslist is always an option if you plan to sell your X-Fi.
I just thought the question was already answered in the last thread you started. For you to start a new thread on this put me under the impression you might not have read the replies to the last thread.
Also you have not mentioned why you won't use 6-channel direct. Is it two wires too many?
