Tonearm Parallel?

Interesting link, interesting videos. So many variables to get the sound right from the cartridge through the tonearm and the phonopreamp….
 

I have a program to do adjust adjustment. Once it is set for with the bajonett headshell for the various cartridges its done. The VTA you would have to adjust everytime you change the cartridge. It will obviously also change with the tracking force you apply. That looks very time consuming considering each cartridge has different height which changes the vta again..

I guess getting the VTA horizontal with the highest cartridge and adjusting the tracking force of the individual carftidges will bring me close.

Otherwise i would have to stick to 1 cardtridge and optimize it.

The SRA needs to be 92 degrees. The arm has to be adjusted to achieve that angle.

How many cartridges do you play with ? 

Suggestion 1 stereo and 1 mono from the same company and possibly even the same model  like Soundsmith Carmen mkII that comes in both or the Grado Prestige Specialty series Gold . This would eliminate height and weight differences.

Just something to think about .

I play 4 catridges, depending on the music I listen. All different sound signatures and varying in height by 1 mm. Benz Gullwing, My Sonic Lab, Van den Hull and Goldring Ethos. 
 

adjusting each time would be a pain..

Nice cartridges ,   my experience with setting the VTA parallel using a 160gr records works very well for records between 120gr and 200gr , I have a few records that are very light at 105gr that sounded bright .  

Using John Denver's "Poems, Prayers & Promises" one being a US Dynaflex pressing weighing 105gr and the other being a German pressing weighing 150gr the difference was noticeable but now as much as one would think . I've thought about trying to use a 150gr record to set the VTA but for now I think I have a few more 200gr records than 105gr ones so for now I'll keep 160gr as the middle or compromise setting .

Good Luck
