Dear @fsonicsmith : Using orthodox tonearm/cartridge alignment set ups every time the tonearm effective length change it changes too the off-set angle and P2S distance.
You said you changed at random your tonearm/cartridge efective length with out other changes but: " VTF, VTA, SRA, and azimuth. " and I understand that you can’t detected differences in the SQ and " defy " any one to pick out the differences.
Well, I did it (As I said several times I almost always make tests on a different opinion of mine to attest if I’m totally wrong or if I can achieve a better SQ with what other gentlemans explain. ) and compare it against Löfgren A orthodox alignment and in my system exist differences in between the four alignments where the common characteristics of the 3 at random overhang is a tonal unbalance where in the forward overhang high frequencies are more prominently and we can think better than the hf in the Löfgren alignment but after a few minutes we can aware that it’s only with more brigthness due to higher resonances/distortions. We have to remember that with cartridge at headshell forward position we are changing too the inertia moment ( effective mass and the tonearm cartridge resonance frequency value. ).. The back ward position is almost " unlistenable " in comparison and in both extremes the bass range is a little bloated in comparison with the Löfgren. There are other things that are more subttle in differences.
I did those tests using my self developed process that includes almost always the same parts on each same LPs tracks and I did it with that process because is the way I know what to look for on each of them The process is full tested in my system and other system and almost bullet proof.
As always I did it at near field seated position and at normal position too.
As you I re-set the other parameters but the off-set andgle and P2S.
Again I’m not questioning what you listened in your system and for me is very hard to think that we can’t detect SQ differences changing tonearm/cartridge effective length at random with out touch the other orthodx related parameters and that’s why I made those tests and confirm that at least Löfgren A alignment makes in my system a better " job ". So, I will stay with the orthodox kind of alignments.
