| Discuss The Viv Lab Rigid Arm Hey all, Another problem I am having with this discussion is the term 'distrotion' is being used way too generically. I believe that the original use of the term by Löfgren etal was referring to THD caused by having a HMA (horizontal modulating ... | |
| Discuss The Viv Lab Rigid Arm @mijostyn How do you know you actually have the alignment you say you do? Here is a test report of three random samples of stylus assemblies from an order I placed. This is representative of the best numbers I have seen thus far and are kind o... | |
| Discuss The Viv Lab Rigid Arm The fact that the Viv arm sounds good to some people speaks to the lack of sensitivity our ears have to the distortion created by zenith error. It is well made and trick which helps. @mijostyn While your supposition above seems plausible, I ... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas Well, something to share with you is that I just finished my listening tests making on purpose a 2mm overhang error and other test changing only ( what more or less permits the headshell ) the angular offset. I think you need to do... | |
| Discuss The Viv Lab Rigid Arm " “From the shape and location of the curves, it results that the largest distortion risk occurs when the overhang is not correctly set for the linear offset. On the other hand, the angular offset itself is not so critical” I don't think when L... | |
| Discuss The Viv Lab Rigid Arm Maybe this indicates that zero tracking angle error is not the Holy Grail some claim it to be. That's the designer's whole point, right? I suspect there are a few other things at play here beyond the TAE vs. skating force. From personal exp... | |
| Discuss The Viv Lab Rigid Arm Hey Lew, This arm is a paradox. It clearly does not appear to have the same 'weighting' for TAE as a conventional pivoted tonearm. Mijo mentions above that there is skating in all non-linear trackers but I think it needs to be clear that the na... | |
| Discuss The Viv Lab Rigid Arm please check. if you can trust the math it seems that putting the null at around 72-75mm will net the best overall compromise. Below is what 72mm looks like compared ot 99mm and a typical Lofgren A. dave | |
| Discuss The Viv Lab Rigid Arm Hey Lew.... Great job! Have you seen any mention in the documentation on where they want the null point to be placed? My guess is 2/3 to 3/4 the way to the leadout is a good start. dave | |
| Which SUT to match Koetsu Rosewood Standard in my system? @elliottbnewcombjr That is the MINIMUM signal strength it needs IN to boost the signal up to line level. does anybody have any documentation on this standard? As stated above it seems all technical but is 100% arbitrary since "Line Level" is... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas Well, don’t tell to me but directly to the SAT designer. I do not have an issue where mark sets his null points and I do not believe he would fudge the inner groove radius to 75mm in the calculations to avoid showing the sharp in... | |
| What is you tonearm’s Maximum Distortion? @lewm I am skeptical in using the calculated number for anything other than crude relative comparisons and find the plots to be much more telling of the relationships at hand. Below are the plots for the table @optimize posted above. From looki... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas It’s only a parameter manipulation Only a parameter manipulation??? If the parameter manipulation is kept hidden then there is another term for it. dave | |
| What is you tonearm’s Maximum Distortion? @optimize in order to enter your desired overhang and offset you need to tick the "custom" option or the program will calculate for the 'standard' alignment ticked. Also the number you enter into the initial arm length will autofill to the rema... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas Since we are considering the theoretical, your proposed alignment simply looks like Löfgren A if you cheat the inner groove radius to 75mm and the outer groove to 143mm which is not realistic for all but the smallest selection of mu... |
