Please Help With Sibilance

Thanks again for all the info guys. I have the cartridge loaded per Peter's recommendation through a musical surroundings nova III. The cartridge I had before this was an ortofon 2M Bronze. I will continue to play records and hope that the sibilince goes away. I know I can tune the bass by tail up a bit but I do not want to amplify the sibilince I'm getting by doing this. I will stop obsessing over it for another 25 hours or so and see if the cartridge settles in a bit.

"Can you please explain what you mean by this? ----->"Realign the cantilever so it's a barely perceptible split hair not parallel to the Feickert" "
Try aligning the cantilever so it is not quite true to what the Feikert suggests. By a very small amount, align so the cantilever rear is just slightly not in line with the stylus tip as it sits on the target. The sibilance should improve to one side of parallel and worsen on the other. Alignment is by far the most common sibilance problem. Once the sibilance is solved, distorted peaks (break up) on hot recordings can require even more dialing in - and luck.

Billo,
Thanks for the suggestion. Right now the cantilever is perfectly aligned with grid lines and the sibilince is dead center in the singers voice. Not off to right or left at all.

Typically Azimuth pulls vocals to one side or the other. Alignment is sibilance and break up. Raising the VTA does not increase sibilance, it subjectively decreases and tightens bass so the sibilance is more apparent. I've never cured sibilance by break in. Analog is no easy road - Bite the bullet, do what you have to do, as many times as necessary. If you're good it'll take half a day. If not, do it experimentally over time.

Just covering the bases - I don't know how experienced you are. Did you immobilize the platter and remove the arm to set the Feickert pointer directly over the pivot spike? If not, that's the problem.

I've never uploaded pics so I hope this works. I removed the arm and set the feickert directly over the pivot spike. Here are my current alignments with lots of sibilince. The cantilever looks to be angled ever so slightly to the right. I am going to fine tune the alignment today. Would this tiny amount of tilt cause sibilance?

Any misalignment can cause sibilance.
You're at step one - overhang. What you're looking for there is the stylus exactly center target and the cantilever is parallel to the lines. If either is the least bit off, so is the alignment. At steps 2 and 3 the cantilever should be parallel at both null points. Look at the cantilever from the front if you can. It's easier when you can see the lines.
Also, make sure you have no anti-skate. The stylus should not deflect inward or outward when it's set down on the Feickert.

I understand the alignment process. I was just wondering if that small of a deflection to the right was enough to cause sibilance. I am going to fix the alignment now to see if it clears up. Thanks for all the info.

The cantilever is true enough in your photo for setting overhang (step 1). The actual alignment is happening at step 2 where parallelism is much more critical. It's impossible to tell from the photos.
