Decca London Super Gold Compatibility Question

The Decca is a quirky design. It has different horizontal and vertical compliances. So neither a low mass or a high mass arm will work optimally with it. The best arm for it might be the Sony Biotracer (on the Sony DD TT). This advanced-design arm has the ability needed to compensate for the Decca's wayward-tracking in both horizontal and vertical planes! 

I have the Sony Biotracer TT in my collection. It would be the only TT that I would trust to use if I had the Decca.This may be a great cartridge (as some claim) but its significant design problems preclude easy set up! 

I used a 12" Jelco 750L for years with excellent results. Now an 12" 850L with even better sound. I had a Decca SG in an Ittok once and it wasn't a good match. It would jump out of the groove sometimes and break up on Zamfir's pan flute.

I have a maroon in a Naim Aro unipivot, I had to drop the back of the arm by a mm or two to get the sound to fill out and there is a definite sweet spot for VTF and I have to make a new arm board to get the overhang right. Even with overhang 2mm too much I’m enjoying the result immensely, bar a little coarseness at the start of a side because of that overhang error but the sound has a lot of presence notwithstanding that, I have the red plastic bracket and the cartridge just slides up onto it, I had to reseat this as it moved a bit when I took the cap off and I didn’t get any sound at first. I remember it sounded thin before dropping the rear of the arm.
