Now, what I was thinking is that in a wrong set up exist an accumulation of " errors " on diferent parameters that even if the SPL is not impaired we can perceive the sound as unbalanced one.
I think that blueranger can take the " short/path/road " to fix the problem:
- listen in the same analog rig a diferent cartridge looking if exist the same unbalanced quality sound.
Here he can discern if the problem is in the Ortofon Cadenza Bronze or not
- Listen to his CD player looking for that channels unbalanced sound. If persist then is not a cartridge problem or phono stage problem but: line stage/amplifiers or speakers or even some kind of problem in the tonearm.
From here, he has to follow tests on each of those single system chain links.
Now, we can follow give any kind of advise to blueranger but it's not easy for any one of us to say with precission where is the real trouble.
Regards and enjoy the music,
