It should work pretty well with that arm. Try the SME headshell. Maybe add a little mass.
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.
