If your alignment is *close* to correct it is likely not the culprit. How much does your 'dressed' headshell weigh now?
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%?
