Well, I say it's a great article cuz I accept it.
I'm sure alot of you have already read it, if not then waste your next 10-15 minutes. Took me an hour cuz I had leftover KFC for breakfast and I read slow.

Thanks JRA for the link. I have not read the complete article but I will later today. What caught my eye was the following;

SRA/VTA matters of course, but in the real world not THAT much, rigidity, simplicity and lateral alignment are all more important.

Hmmm!

JM,
I figured you'll get a kick out of it. I still believe(for now) that it's important to set VTA within 1-2mms for different record thicknesses.
But, I agree with you. Other factors should be considered more analy.


"The VPI's VTA adjuster clicks equate to 0.35 thousandths of an inch according to Mr Gregory. As there are 26mm in an inch that translates to 0.00035x26 = 0.0091mm, i.e less than one hundredth of a mm... He says that changes of +/-2 clicks produce a "vital" change in sound quality. So once you've found that sweet-spot a change of 0.018 mm (2x0.0091) will lose that perfect reproduction. Now just to drive that point home that 0.018 mm equates to a 0.00342 (0.19x0.018) degree change in SRA. Just over THREE THOUSANDTHS OF ONE DEGREE!"


Isnt that amazing? That Roy Gregory has the Ears of Gods!! LOL
