What's a real good arm for a Decca Cartridge?


I have a Decca London Super Gold with a paratrace stylus. It's sound as good as anything I've ever heard using my SME M2-12R arm on a rebuilt TD124. The problem is I want something that will track all my LPs and the SME just won't. After a bunch of tweaking, including adding tons of mass, it'll play 90% without issue. What arm will get me those extra 10%?

I run the same DSG/wP in a Jelco 850L with no tracking issues and sounds superb.
The Biotracer arm on the Sony DD TT. Servo-compensation for better groove tracing and elimination of arm resonance matching for different compliance cartridges. The Decca cartridge would certainly benefit from this, as it has much different stylus compliances in the vertical and horizontal planes!

Sorry for not remembering the model number of the Sony Biotracer TT! I do have one on hand in the other room! Pretty neat arm!
