Help with getting shims for my Ortofon Cadenza Blue.

I have a Technics SL-1200G with a Cadenze Blue.   I haven't bought a USB microscope yet, but it looks like I have too much VTA.   And I have a Ortofon LH-9000 headshell.  Even with my tonearm is all the way down, I seem to have way too much VTA.   The bottom of the cartridge is parallel to the record.

I think I need something like a wedge shim to lower to back side (closest to the tonearm pivot point) of my cartridge.   Can anyone give me some recommendations.   Or even heard of too much VTA

I broke my cantilever on my Cadenze :( and just got it back from a repair at SoundSmith.   Maybe I do need more break-in hours and see where VTA settles in at.   I bought a digital microscope yesterday to see where VTA is, but currently I don't think it's near 90 degrees to the record.   Once I can get it to near 90 degrees I'll use my ear to adjust it.

i have the cadenza blue on a technics also.  use the stock headshell because it puts the cartridge closer to the platter.  i use one shim to keep the azimuth ridge out of the headshell recesses.  
for a great starting point put a small round bubble level on top of the headshell and adjust vta dial until it is level, assuming the platter is level, stylus in the groove of an lp and VTF adjusted to compensate for the weight of the bubble level.

sra  should be close to 92 actually  that's how they cut the vinyl.


when they stylus drag with with vinyl playing. the sra will also reduce, {unless it a real stiff cantilever and suspension} after burn in it also be reduce . so don't worry about too much sra. even at 94 or 95 it's still sometimes be ok. just listen after burn to it until the hi freq sounds right. then adjust

instead azimuth is more important. use the scope will get you close.

Thanks avanti1960.   I’ll switch back to stock headshell.   Weird that there is any recess in the LH-9000 for using with the Cadenza.    But there is with the stock headshell.   I’ll get this shim.   Been looking forever for one.
