| What is you tonearm’s Maximum Distortion? @rauliruegas Forgot that if you want lower distotion figures then and using Löfgren A alignments its tonearm parameters set up are:overhang 21.58mm and offset angle 24.8°. Where the maximum error 0.94° maximum distortion 0.33% and ave... | |
| Discuss The Viv Lab Rigid Arm @maxson The less the underhang the closer the single null point will be to the runout groove. It is also important to pay attention to the cartridge zenith since a slight offset of the Zenith from 0° will have the same net effect as a slight ch... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas As any can see it needed only most inner/outer groove radius and nothing else. This will give you the theoretical placement of the null points. Nobody is debating this. Again the topic at hand is actually placing those null poi... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas for some reason you introduced this particular tangent in response to me simply mentioning in order to get two null points both overhang and offset are required. In this thread on feb 14 you wrote: Anyway, for me the VIV/underhun... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas then please kindly explain to @dover how to use the null point formula you presented to set the two null points for the arm with zero offset. dave | |
| Discuss The Viv Lab Rigid Arm @rauliruegas specifying a formula and not understanding its relationship to the discussion at hand serves little good. I doubt Løfgren would suggest it possible to get two null points without the addition of overhang no matter how much you poin... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas You have stripped all context from my original quote which was about the requirement of both overhang and offset to get two null points. Without overhang which requires an effective length to calculate the two null points cannot e... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas Null points calculation it not depends of any other parameter, not even tonearm EL. Whaaaa??? you need to specify at least four parameters which typically are alignment type, inner groove diameter, outer groove And Pivot to sp... | |
| Discuss The Viv Lab Rigid Arm @dover I am suggesting keeping the headshell offset at 0 ( straight ) move the arm mounting point forward in order to set 2 null points. The combo of properly set offset + overhang is the only way to get the 2 null points. If you eliminate e... | |
| Discuss The Viv Lab Rigid Arm Ahh like the old Vace-Fase illusion you get a 50-50 shot at getting correct. I did a google image search and got about 3 images into an online test and it was funny how you would look at the image and then tick a checkbox from a list of possibili... | |
| Discuss The Viv Lab Rigid Arm Math without an attachment to a subjective listening experience is only worth the computer screen it is displayed on. Your Rorschach reference is a perfect one for this situation and you seem to be the therapist explaining to the patent what they... | |
| Discuss The Viv Lab Rigid Arm @lewm My best guess is for some reason the underhung arms handle the TAE differently than a traditional arm. I think i would liken the sound to that of the conical vs advanced profiles. In all but the best setups the conical will sound better ... | |
| Discuss The Viv Lab Rigid Arm All of the offset is applied at the single mount screw. The only thing preventing a 0° offset is the back of the cartridge hitting the armwand. I made a shim to get the clearance so the cartridge could be set straight. I looked at the math an... | |
| Discuss The Viv Lab Rigid Arm @lewm Mijostyn’s position could be turned on its ear: you may be used to certain distortions created by overhung tonearms that you “like”. you mean like skating forces causing the TAE to change dynamically with modulation levels? I spent an... | |
| Discuss The Viv Lab Rigid Arm @maxson Thanks for confirming. I suspect it is this additional ability for movement that plays a big part in the arms response to and recovery from movements that cause mistracking. dave |
