Dear Doug: My experience and answers from manufacturers were for the active devices.
I don't know about the Cardas passive device.
What I know, active or passive, is that the question has to be answered by the cartridge manufacturer. Not a dealer not any one of us.
The cartridge manufacturer is the person that has all the know how about and in particular about his cartridge.
+++++ " How would that harm a cartridge? " +++++
You don't know for sure, the cartridge manufacturer has the best/safe answer. Not you.
Regards and enjoy the music.
