"I got minimal crosstalk with the cantilever very close to perpendicular to the record surface."

Having difficulty visualizing this geometrical relationship.

Having difficulty visualizing this geometrical relationship.

Imagine you are looking at the cartridge and cantilever from the front. If the motor is perfectly aligned with the body of the cartridge, the cantilever will appear to be normal to the LP surface, ie, perpendicular.

The words "will appear perpendicular" did the trick.

Why is it when someone gives the Transfiguration cartridge history lesson the
ARIA is always left out?
You can even go to the “way back machine” and look at Immutable Sounds web page and there is nothing about it other than an announcement sayin that it will be introduced “next month”
Then nothing..... I have emailed them and was told “we have no information on THAT cartridge”
Very strange response....
