Dave,
Behavior like that is "by definition" intermittent (sometimes it works,
sometimes it does not), and usually can be traced to some connection.
Do not ignore the connectors. Usually, they will wipe off any oxidation
by simply removing and re-seating, but at times, more drastic action is
needed. Try putting a tiny bit of contact cleaner on the pins and
before it evaporates, insert it into the socket.
If properly mounted, the KDSP2 should not contact the KPA100 speaker.
If it does, I must ask if you are using the stock standoff on the
Control Board fastener? You can remove the left side panel to check the
clearance.

When it does boot up it works perfectly. Often it doesn't boot which results in no audio out but when I power the K2 down and then imminently back up the KDSP-2 starts working normally.

I did have some problems with the KDSP-2 shorting on the speaker of the 100 watt amplifier heat sink but I have fixed that. When the KDSP-2 is working it remains working even when I subject the K2 or the KDSP-2 to some small knocks or vibration, so it is not an intermittent connection.
