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

Pardon,87v is the correct one.To late for me.

If this is correct,it is low ohms for the Lyra Titen.If I have the correct one.[http://www.audioasylum.com/cgi/t.mpl?f=vinyl&m=940292]

Hifihvn, all of the specs that I've ever seen for digital multimeters do not provide enough information to determine the safety of their resistance or continuity functions with respect to a LOMC. The things that have to be known are the voltage the meter puts out into an open circuit when in those modes, and the output impedance of the meter when in those modes. That information together with the coil resistance specification of the cartridge would allow calculation of how much current would flow through the coil.

Without intimate knowledge of the design of the cartridge, it would then still not be possible to precisely say how much current would be safe, or for how much time a given amount of current could be safely applied.

The meters on analog multimeters typically move to full scale (which would indicate 0 ohms for the ohmmeter function) when the current flow is somewhere between 50 ua (microamps) and 1 ma (milliamp). The Lyra Titan i cartridge is spec'd to provide 0.5 mv (millivolts) into a load that can be as low as 10 ohms. 0.5 mv/10 ohms = 50 ua. So an analog ohmmeter for which 50 ua results in full scale meter deflection would certainly be safe. But one which required 1 ma for full scale deflection would be putting 20 times as much current through the cartridge as it would normally be called upon to provide under worst case loading.

Almarg,Thanks for the info.It would help if they did give more info about Digital Meters.I can't find any info either.I think the info that came with my meter,is the same as they provide on the net.They seemed to help phase out Vacuum Tube Voltmeters.I hope I don't ever run into this type of situation.

Forgive someone who has NO ee knowledge from chiming in, but you may want to consider contacting member jcarr who, IIRC, designs and manufactures Lyra carts.
