Ortofon as309s or sme m2-12r

I use a RS309D. The VTA adjustments are easy and convenient.
Get the RS series rather than the AS series.

RS series already equipped with the correct counter weight to cater for heavier carts, whereas the for AS series, you would need to buy another additional counter weight

Doesn't the Ortofon arm use the grub screw on the pillar method for VTA adjustments, in which you loosen the screw and manually slide the pillar up and down? To me, that's not very convenient. I prefer methods that are mechanically controlled for fine, repeatable changes.

Is and why the rs309d worth the extra cash over the as-309 or the SME m2-12r in your opinion ?

You guys are bad, making an old man lust after an RA309D .

I am also looking at a similar choice. Ortofon or SME.
Ortofon is known to be a Jelco with probably a better internal wiring and some additional adjustment features above the stock Jelco 750D tonearm.
SME on the other hand is of course more reputed for their analog products. The M2-12r is one tonearm which many prefer over the SME V tonearm. That gives it more credibility.

But in the end how different are they sonically, I do not know.
