53E7:  I finished the cable over the weekend. It actually worked great.  If I ever need another one, I’d try and source a different housing for the cable. It was a REALLY tight fit.  This was a fairly inexpensive project.  l had all of the cables and most of the connectors, left over from projects over the years. 

I used an old Apogee cable cut in half for my SP/DIF in and out. The other cables are audiophile silver conductor cable. If you are going to do this be sure to buy a few extra D-Sub connectors. 

Dante:  So I take it there were a few challenges the first couple of times?

53E7: It took me three connectors to get to the final breakout cable. The pins easily shift around when hot so you need to be very careful. You should be highly skilled with a soldering iron. This would not make a good first soldering project!  Here are the D-Sub connectors to the right. I bought them from an eBay seller in Taiwan.  Below, my rationalized rear connection set-up! 

Below is the final cable.  Simple and uncluttered.  Just what I wanted!
