Dave - I can only imagine that by feeding BOTH 5V outputs in parallel from the power supply to the Touch you are managing to provide enough current to drive the Touch. It won't hurt anything (if nothing is even warm then things should be fine). -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
