Testpilot,
Why are you so angry? The only "slamming" in this thread was your tirade that brought nothing to the discussion. But thank you for telling us that apparently you're having a bad day, or are an angry man in general, or both.
At worst, I criticized VPI for providing inconsistent data, which is understandably frustrating and nothing new. The Classic tonearm WAS mounted with a S2P of 262 mm at some point, and Ken Willis still makes two protractors for the Classic tonearm based on two different S2P distances (258 and 262 mm, not to mention Yip who apparently uses 259 mm) so my skepticism was valid, and measuring can be tricky. I have no problem with a manufacturer changing specs on their product, but a heads-up for the customers would be nice (e.g., through adding an identifying symbol when a product is changed). The very tonearm in question is a good case in point as good luck finding its true effective mass, and which version you actually have if you're a Classic turntable owner - aluminum, steel, a combination, a combination with more damping? So yes, I did dismiss the data provided by VPI based on my experience, but did not slam the poster.
Similarly, to say that the article on Vinyl Engine was based on the wrong info is just nonsense as when it came out it was based on the specs released by VPI and on the measurements of their own jigs. The article might have less substantive validity today after VPI apparently changed some of their specs, but it certainly makes a valid point regarding lack of transparency and confusing information from the manufacturer. I love my turntable, and think VPI is a great company, but I wish they made it a bit less frustrating for owners of their products in this hobby where great accuracy is the key to the desired goal of faithful music reproduction.
In the end, all was clarified, and I see no confusion, just a lot of good info and a cordial discussion. That is until you decided to change that. So thank you very much sir. I hope you feel better now.
