I am at the end of my rope, please help

I have a problem that I can not solve and makes no sense to me at all.
My right channel is stronger than my left by a large margin. I can plug my tonearm cable directly into a Fozgometer (measures left and right output) and I get a substantially stronger signal on the right side. I confirmed this with my Voltmeter to make sure there was not a problem with the Fozgometer. So, as far as I can tell, this narrows the problem down to the Cart, Tonearm, Tonearm wire or the table.

Here is what I have tried:
1. Changed Azimuth in both directions. Small change but still much stronger on the right side.
2. Changed antiskating. Very little change.
3. replaced the cartridge. No Change.
4. replaced the tonearm and cartridge. No Change.
5. replaced the tonearm, cartridge and tonearm wire. No change.
6. I have used a second test record. No Change
My turntable is perfectly level.
I simply do not see how this is possible! I have an $83,000 system that I can not listen to. Any ideas would be much appreciated.

My system:
DaVinci Turntable > Lyra Titan i > Schroeder Reference tonearm > Manley Steelhead > Stealth Indra cables > VTL 450 amps > Stealth Mlt speaker cables > Vienna acoustic Mahler speakers

Did you perform the checks with the Fozgometer and the voltmeter AFTER performing all the replacements and adjustments that you described, as well as before doing them?

If not, consider the possibility that there may be two problems present, causing similar symptoms. So the replacements or adjustments might have fixed one cause of the imbalance, but not a separate problem further downstream that may be causing a similar symptom.

That would seem to be pretty unlikely, but given all the things you have tried, whatever the explanation turns out to be will probably be something unlikely.

Swapping channels at the Steelhead inputs would be the obvious way of either ruling out or ruling in that possibility.

Good luck!

I knew when I saw "I am at the end of my rope" that the post was going to be a turntable problem!

Try switching right and left cartridge clips to see if the opposite channel is weaker. If not, the problem may be in the phono stage or preamp. Switching R&L cables on those starting at the highest point in the chain will further isolate the symptoms. Also check all cabling for solid connections,. I empathize with you. Sorry to hear your having trouble.

You posted on VA as well, and I took a shot at it there. But now I see something that eluded me previously. You say both here and on VA that you took your measurements directly off the tonearm wiring. I now see also that you changed BOTH your tonearm AND cartridge, and the problem persisted. If you did these two things simultaneously, that's whacky. Now I see why John Ellison focused in on your ICs. IF you have been using the same pair of ICs throughout, try another set whilst keeping the second tonearm/cartridge combo in place, or simply swap connections at both ends of both ICs, one end at a time. (IOW, at the tonearm end, swap leads between L and R channels. Listen. If the weak channel does not swap sides, then swap leads between L and R channels at the preamp end. Listen.) This will turn out to be something simple and benign, I am sure. Well all of are giving just about the same advice. So we cannot be wrong, can we?

Try reversing the polarity of one side of the cartridge i.e the right-hand side,at the cartridge.Then reverse the polarity at the right-hand speaker to return to correct polarity for playback and then take your measurements again.This is an old tweak from the glory days of vinyl to help minimise fluctuating polarities that occur inside amplifiers.It is something I do that has improved the fidelity of my vinyl playback.It just might address your problem.
