Well,
I started with the wiring instead of the DAC. 1/4 through in maybe 30 mins, but now that I know exactly what I'm doing it will go faster. I also fixed a grounding issue which has now made these speakers silent (they were close before) at full volume. I can't even listen near full volume! Installing the ground was a true PITA. I can't access the ground on the IEC easily so I hard to figure something out:
4 hand cloths - to prop open the lower lid. It's hinged but only opens about 3" as it is restricted by the transformer wires.
2 flashlights - so I could see what I was doing in the box.
1 bent nose pliers - to hold the wire while I soldered
A lot of sweat!
It was tough, but in the end it worked out fine. I tested with a ground outside the box to see if it would help improve even more by installing it on the right side as well. With there was no audible difference, I think I'm just going to go ahead and do it anyways. Can't Hurt.
Here is what the amps used to look like: (this is the right side, but both sides were essentially identical)

Here is a close up of the left side:

Here is the left side I've done, gives an idea of the finished product:

Notes:
1) The patched wire visible in the second photo will be fixed. I doubt it is effecting sound, but I might as well deal with it.
2) The loops of wire visible are for the LEDs I haven't yet hooked up.
3) Black techflex is power, Green is signal. I tried crossing at a 90 and it made no difference in sound. Therefore I left them in the easier configuration.
Off to dinner. I shall finish upon my return.
