" Example: when we change VTA/SRA the AZ changes too "
It is obviously apparent from this claim that Raul is not well informed about the intricacies and standards involved with properly installing and aligning a phono cartridge/tonearm assembly as part of a Music Reproduction System or there would be no way Raul would make this claim. Now it is possible that Raul has achieved this observation soundly through analysis of his own phono cartridge/tonearm assembly in his Music Reproduction System but for that to be true he obviously has a damaged or defective or faultily designed tonearm because of course if the tonearm is properly manufactured and is not suffering from damage then changes to VTA/SRA will not effect the azimuth this would be true even if the azimuth of the phono cartridge and/or tonearm is defective. To restate it in other words azimuth is independent of these other variables and frankly for someone such as Raul who claims to be a guru of sorts with phono cartridges this claim undermines his authority at least as much as his claims about phono cartridges that he has purchased used that are decades old and so have in most cases certainly decayed as a result of age to the point where no one can reliably draw any meaningful conclusions about their performance.
