You did a good job on the digital connector on the dock and the slot cover mounted connector.

Thanks for the tip on the S/PDIF. It was there all along. I was looking for "Digital In" or "S/PDIF In" somewhere and couldn't find it.

And about your Senn HD-590s. I'm sure they sound great. I have a pair of HD-600s and they are by far the best (and most expensive) headphones I have ever owned.
