Thank you so much for clearing that up Mr. Pass! I have read over and over again that cartridges are inherently balanced, even from some respected manufacturers. Not that I know very much of anything about audio engineering, but what you say makes a whole lot of sense. I appreciate your taking the time to respond to my query.
Thank you for making so many of your wonderful designs available to the DIY community.

i think the balanced idea comes from the cart's output being AC, but it is floating without a ground reference. Something that a center tap transformer would give.
Mr. Pass, it sounds as if you are reluctant to use an input transformer. If so, why?
That would give common noise cancellation, and a balanced output, or?

They are in principle, but the grounds are almost always tied to the metallic case that connects to tonearm and therefore to safety ground of the turntable/phono pre.
So, everybody is right 😉
Have fun, Hannes
Hi,
I don't know your specific cartridge (maybe metallic mounting insets? Or metallic top plate?), but there exist balanced cartridges, or in different words, there exist people modifiying their (metallic) cartridges to balanced by cutting this connection.
Cartridges are not by themselves aware what ground is. It's done on purpose.
Have fun, Hannes

PASSDIY Attack Site?
I went to the Pass DIY site and was repeatedly warned that it is an internet attack site that tries to steal personal information. Anyone else getting that message? Thanks. I'm presuming that the new pearl/ono boards are not yet available?

I´ve got a warning from avast antivir about a trojan horse at passlabs.com
Are there attacks against pass diy and pass labs sites, or is it false positive?

I have the same problem: my web browser (Firefox) suggests that Passdiy.com is a malware website
