I have the amp stand version of what you have, and the brass points I am using were the ones provided by Sound Anchor. They may be audiopoint brand, I do not know. The silvery ones you describe are most likely Sound Anchors steel version that are adjustable by threading them in and out and locking with a nut.
If you are satisfied with the present set up, I would not be too concerned. The only reason I brought up the subject of other cones was to suggest that the gains you got with a first time trial might even be improved by experimentation.
