The Data Only USB cable contains simply 3 wires, data plus and data minus and a ground wire. This is our best performer overall.
If your DAC can accommodate this type of architecture, then this is the preferred way to go.
The Standard JMaxwell is for those DACs that require a 5 volt leg. The Vbus is shielded from the data lines to help aleviate EMI noise
from affecting your data stream. The data leads are the same in this wire as in the Data Only JMaxwell.
