Rega Ania Cantilever Bent?


I bought a rega P6/Ania combo and I just cannot get the sound right. The left channel sound 30% weaker than right channel. I checked the alignment (using Rega protractor) and tracking force (~1.9g) and I switched input for phono preamplifier and the sound problem did switch. So the problem is from turntable. Then I closely looked at the cantilever and noticed it is “bent” slightly inward. (Picture attached). Could any Ania owner help to confirm if it is bent or it is made in that way. (From stock picture , it is straight and right in the center) Thanks.

Some said if antiskate is too much, it may cause the “off center”! Cantilever . Currently, it is set as 1.75 as Rega suggested. Not sure if I should reduce it further? 

Reversed? You mean the connections on cartridge?  Thanks
Go through everything from scratch. If not fixed, call the dealer before you bust something! Something is not right.
One correction. It is right channel(red RCA connection) weaker than left channel. right channel is actually from the outer side of groove based on the discussion I read online. it may be consistent with the fact that cantilever is bent inward toward center. 

I will try to switch the connection in cartridge to identify the problem is from off-center of cantilever/stylus, not from tonearm wire.   The cantilever is off center already when I received it.  

Any thought or suggestion is welcome. 
 
Just switched the cartridge wires (right<--> left) . and problem channel is switched!. I think this confirmed the problem is caused by the cartridge
(off-center cantilever).   Any suggestion?   Thanks
