Help with getting shims for my Ortofon Cadenza Blue.

use your magnifier on handphone to try. place it on blank cd. and reduce vtf to half. anti skate off
roughly it can be seen. but ortofon is not easy to get vta right they have quite soft cantilever. they will change when stylus is playing . normally 94 95 is ok for a start. when broken in it will go 91 92. so too much is usually ok 

your assuming sound is brittle and gritty  too much vta? sometimes it's just new.. need 40 hours of play time before serious listening

azimuth is more critical.. actually. 

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.
