Straightwire Maestro vs Maestro II?

Does anyone know the difference between these models for interconnects?

I don't know about Maestro but i can tell you there is no difference in Crescendo and Crescendo II wires.Just different serial numbers.
I should contact Overhang.

Maestro II has lower capacitance
due to a change in the microporous foam Teflon insulation andslight change in the individually coated conductor strands.

The latest version of Maestro is a dual symmetrical coax that can be used for balanced and unbalanced applications.

Feel free to email me for more details
