SAEC WE 506/30 incoming. Anybody here with any experience with this arm?

@lewm 

Thank you very much, very interesting!

I have no intention of trying to calculate an other alignment for the 506 as Dertonarm has, but it`s good to know. 
Vinyl Engine, however, does have a calculator showing offset angle and overhang for the different geometries, including SAEC`s own, on the 506. A good starting point, I believe.. 
I have several headshells lying around, so the ceramic headshell is/was not an option.
I guess that the best way is simply to try the arm out. Thanks again for your help.

Short update:
Everything takes time, but the SAEC 506/30 has now arrived and is mounted. A very good arm IMO, although I have no experience with other 12" arms. 
Re. Geometry: Stevenson alignment comes almost naturally to this arm, with an infinitesimal angling of the pickup in the headshell.  

I have tried out three different carts: FR Mc-1 Mk.iii, SoundSmith gold DL 103 R and Accuphase AC-1. The Accuphase has a bit higher compliance than the other two, and shouldn`t work that well in theory, but it sounded the best of the three.

I have just seen this thread, and have used WE506/30 for several years now. As you now know it does require around 4 degrees extra twist in the headshell. We sell a laser engraved template for this if you need one..

 Once set up, it is a fantastic tonearm, the ceramic headshell is ok but can do better, Oyaide CF is good, as is Nasotec swing, this is what I use. Fonolab do a good arm lift mech too.. Not necessary to stay with low compliance carts, we have used from DL103 to My Sonic Labs eminent to Signature, AT Art 9, Aidas Panzerholz, through to Aidas Mammoth gold mkii, which is simply amazing. It is a bit strange with the offset, but the arm is too good to dismiss it purely based on this aspect..
