Dear Thekong: +++++ " and these curves aimed to minimize tracking distotion in different sections of the LP. " ++++
correct and you can have as many curves as you want depending if you take IEC/DIN/JIS most inner/most outer groove as input to the equations or even your own values. You can " play " about to make calculations make the set up and decide which one works better for you.
+++++ " With the alignment jig that came with the Graham Phantom arm, I can see the difference in overhang of the 2 different alignment curves (forgot which 2) can be as large as nearly 1mm " +++++
that's the difference between Löfgren A and Löfgren B alignment.
+++++ " As such, I am a bit skeptical when some users of ultra accurate alignment jigs claiming they got considerable improvements with these jigs. It seems to me that, even with this ultra accurate alignment, you are simply trading less tracking distortion in a certain section of the LP for higher tracking distortion in other sections! " +++++
right and that is what I understand Dover posted, unfortunatelly always exist trade-offs.
Remember what I posted :
++++ " any change on VTF or VTA/SRA ( if we make those changes or the ones that happen during playback due to the LPs are not flat but full of waves. ) affect the whole cartridge/tonearm geometry set up meaning that distortions values overall the LP surface that were calculated on the choosed cartridge/tonearm geometry alignment has no " value " any more because the starting distortions calculated were on " perfect conditions/theory " in a STATIC way not DYNAMIC as during playback.
So in reality we are almost at random ( during playback ) about those tracking distortions generated on a pivoted tonearm choosed cartridge/tonearm alignment.... " +++++
Btw, Halcro you can manipulate any of the equations parameters only if you made the value changes in the other equations input parameters and the set up was made it with the new calculated parameters. If not everything is wrong, you can'T manipulate the overhang parameter with out the choosed equations new calculation. This is not aritmetic where you can add or rest somewhere and think that all is preserved but the overhang: mistake.
Anyway, I don't care what you are listening because I don't have to live with, as Dover I'm only trying to help.
Reggards and enjoy the music,
