Channel frequency range not balanced

If you swap the channels at the cartridge, in the headshell, does the bright channel move to the other side? If so, it’s the cartridge.

This.

Thanks very much,yes I will swap the cartridge leads,if this points to the cartridge i will use fine shims to hear if azimuth adjustment is the solution.

Hi,
i believe that you did not have the same problem with your previous cartridge and retiping was performed accurately.
Do one step at a time, most probably cartridge is out of alignment on lateral axis, another cause would be different tube (not same construction) in phono preamp (if you are using a tubed unit).
Azimuth would be the last thing to check and only after everything else is properly set up.

Hi, well if anyone who kindly answered is still following, I performed another full channel swop from top to bottom, except that this time I swopped the cartridge channels as suggested here.
Without doubt it is my left speaker that is at fault. However an unexpected benefit came about when I replaced the cartridge wires in their correct order. Suddenly the soundstage `sharpened` up for lack of a better description. The stage became more focused, slightly narrower but more specific. 
Good old vinyl!
I have a pair of demo Monitor Audio SE200`s on hold for the near future, looking forward to that.
