Classic match for the Decca was something like Hadcock 228 unipivot. I've used Decca since 1978 on a Hadcock with silicone damping - Maroo, Garrott Brothers Gold and a John Wright rebuilt C4E.
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.
