The additional power supply arrived for my d1 server yesterday. I had to remove the lid which was relatively straightforward using the enclosed screwdriver and small allen key!
Once inside the unit I had to disconnect one jack and connect another. See guide here:

So now my d1 server had 2 external power supplies! I powered everything up and played some music just to let things settle for a bit. About half an hour later curiosity got the better of me and I sat down to have a listen.
I know there is a tendency to get carried away with the superlatives when describing a nice improvement but wow this was dramatic! I certainly hadn't expected this.
My d1-six has now reached an altogether new level of performance that is simply astonishing.
Almost the sort of improvement I would imagine one gets from going from a d1-six to d1-twelve!
