I received my chinese 30K galvos yesterday. I will give a review once I have more time to use them. In the meantime, I have a question about the cable between the DAC and the scanner amps. The wire that came with the kit is just normal straight wire but my other scanner set had a shield wire for this. What do you guys use between your DAC and amps (or your DB25 connector and scanner amps if you don't have the DAC in your scanner enclosure)? I only need about 1 foot of wire to reach between the DAC and amps. Is shielded even necessary?
