SAEC 308N vs 308SX

Dear Lewm, the V-Blocks inside the SX model are made of ruby just like in WE506 & WE8000ST and the whole bearing is encapsuled for protection.

Dear Lewm, mind that if you ever go for any variation of 308, you cannot use the ULS3X ceramic headshell on it. You have to purchase another slotted headshell, in order to make the Baerwald alignment. You must turn the cartridge another 11 degrees to the spindle side at the headshell. The ULS3X is great for any other arm except SAEC. I've seen it priced up to $450 so, you can allways put it on sale, or keep it for some other vintage arm of your's, but on the SAEC it is completely useless.

Dear Lewm, the ULS3X permits back & forth movement but not even the slightest twist of the cartridge. I would never imagine Raul to accept this kind of distortion as the above graph demonstrates so, I don't thing that he prefers this ceramic headshell on any of the 308 arms. As for me, I've never gave a chance to compare the SAEC alignment in my second armboard, with the ULS3X headshell (I 've keep it undrilled till today). The null points indicates a unique optimisation at the inner groove, but not a Stevenson align.
Now about the twist of the cartridge on the headshell, Daniel & John were in disagreement about the effect and if I have to choose between a tracking error or a mechanical paradox ... you get my point.

Have you verified the pivot to spindle distance in your second armboard? Is it in agreement with the SAEC's unique recommendation? If so, then you don't have much of a choice. I remember on most set-ups that I've seen (in photos) that the majority of users accept the std SAEC recom. align. of not twisting the cart. Me too I would like to hear from someone who has experience on both alignments upon a 308. Unfortunatelly I have very limited free time these days for more exploration.

Dear Lewm, all the geometry info is contained into the above Vinyl Asylum thread that I've copied back in my previous post.
Perhaps you've missed this so, please take a good look this time. It contains both alignments. First the SAEC recommendation and then the Baerwald for comparison. The P2S distance is 235 for SAEC and 222.759 for Baerwald. The difference is so great, that you can easily measure your (intended by Kenwood) P2S.
So, once again :
