I finally get it!


I had a long  discourse with VPI after I bought my new Classic 3 Sig SE years ago. The subject was that the S2P distance was off. After over one year of trying to get this resolved, I still received my tt back with this distance 1 mm (long).

I always wondered why there was no forthcoming measurement of the S2P distance. After all, VPI is know to have customers DIY their own tts, based on VPI's own products.

So, VPI offers their set-up jig with new tts. They don't offer any specific measurements for S2P. Someone had to ask on their forums in order to find out. Why?

I now know why. Because, their manufacturing was/is not very precise. So, if their S2P distance was off when the tt left their shop, their own jig (provided) would still keep the S2P distance in a (good enough) range. 

Nice try/trick.

Just curious to the swapping to an Origin Live arm or any other arm addresses the pivot to spindle distance being off, would you not have to have that correct before you install any arm? I personally do not have an issue with the VPI unipivots and run a 9 and the 10 3D in two different systems and suffer the same problem with both on the issue of spindle to pivot being off on their given tables. 
@slaw , that is very good to hear, that good results can be had with the noted discrepancy in the pivot to spindle distance not being as advertised. The issues with both my tables is that the stated spindle to pivot distance is one mm short. Was wondering where yours was when you sent it back to VPI to have them send it back one mm long?
@tooblue ,

It was 2 mm short.

Many people including Mat say this isn't an issue. I say they are wrong. My ears confirm this. I read a while back that Mat said he's made a new jig to address this.
@slaw Go to turntablebasics.com and look at alignment tools. They have a lot of good info about tonearm alignment on their site which may be helpful to you.
