Dear Hanaleimike: Normaly a test record is a help to confirm that we have a good cartridge set-up but at the end our ears are the best tool to decide if what we are hearing is right on target.
There is no reason that a " bent " cantilever preclude to make azymuth changes ( by ear ), so I can't see any trouble with your cartridge where you like its quality performance.
Now, a brand new cartridge ( in theory ) must comes with a straight cantilever and if in your cartridge this is not happening then make sense that you claim for a change of the item according the manufacturer warranty.
If we take the attitude: " that if sounds good is ok ", then the build quality control on audio items can't improve in detriment of us the customers, we have to claim!, especially on brand new items.
Regards and enjoy the music,
Raul.
