I finally got a chance to add some more pictures tonight. 

Here are all the parts that make up the Legato I/V stage.  
  I thought I had this board ready to go but was not getting any sound from the single ended outputs.  After a few minutes I realized that I forgot to install the chokes for those outputs.  Once they were in place it worked perfectly.  I was able to get the DC offset to 0 on both balanced and single ended outputs. 
 This is just to show that I repositioned the relay to make it straight.  I get a little OCD sometimes.
 All the parts for the 4-input S/PDIF board.
 Completed(for now) S/PDIF board.  Inputs 1 and 2 are setup for 75ohm BNC or RCA and input 3 is ready balanced AES/EBU.   Input 4 is left open as it will be used for the exaU2I i2s converter that should be here in a couple of weeks.
 All the parts mounted together on my desk ready for testing.

I did have an issue with it not locking and clicking from both sides.  After some searching I found that the voltage needed to be set to around 4.8v.  Once that was done it worked perfectly.  No lock issues and no clicking.  Thanks to all the guys at the Twisted Pair forum for posting about this.

I'm hoping to have the Plitron transformers in the next day or so and will post more when I have them hooked up.
