Decca London Super Gold Compatibility Question


Can someone tell me what happens when you use the Deccas with the wrong arm? Is it a tracking issue or will it just not sound good? I tried it with my SME M2-12R with a Yamamoto wood headshell and the results were not great. Hoping it's just compatibility and not something wrong with the Decca.

I'll try the lighter tracking (I was at 1.8) and the sme headshell with some added mass and report back. Thanks. 
Some people claim the Decca/London design doesn't like the knife-edge style bearings of SME arms. If you can get your hands on a Zeta at a reasonable price (under a grand), snap it up! Johnnie at Audio Origami knows all about the arm, and has restored and/or rewired many of them. A real good arm for the D/L's.
