Have a record with annoying sibilants as do I, like that horrid Diana Krall Classic LP, "Love Scenes" or Alison Krause/Union Station "New Favorite"? Sibilants were tamed on both using the JMW Azimuth adjusting ring.
I found that leaving the inner Allen Key just loose enough so that moderate pressure was required to move the ring with the outer key loose, just as you do with one of the headshell screws when adjusting cartridge overhang, eliminated overshoot and the need to tighten that pesky inner key every time you wanted to try a setting.
I also pass along the function of the cardboard sleeve the Azimuth Adjusting Rod arrives in as what, in woodworking circles is known as a "Winding Stick". Place the Rod in the headshell groove and the cardboard in front of the cartridge on a record then sight across the top of the cardboard. You will either see the left or right end of the rod visible above the cardboard indicating out of alignment or the rod clearly level in relation to the cardboard.
That done, begin the listening test, and remember, if it were easy, everyone could do it ;-}
