It's sloppy, but you can always solder in wires in place of ruined PCB traces. For the power circuitry, I don't imagine the exact distances and trace positioning mattering in a significant way.

I am finished with assembling the o2 amp but I am having problems with J1. The leads for the power jack are way too big. How did everyone overcome this?

I have already managed to break the jack by trying to crimp the leads to make them fit. Will be reordering that 1 part soon.

I am using the Kobiconn DC power Connector PCB 2.1MM

For low level evening listening I still find myself having the volume control all way to the bottom almost which means I get a little channel imbalances.

I know it's possible to just turn down the volume in Foobar2000, but that degrades the audio quality, doesn't it?

Kobiconn changed the leads a few month back, since then the two pins in the middle are to wide to fit. I use a key file to grind them down until the PCB will be revised.
You need to be careful with the pin in the center of the connector, it sometimes comes off very easy when applying to much force.
