My battle with sibilance.

At the minimum sibilance is annoying to me. Its only present on a small percentage of my records. However today I wanted to see if I could improve it. The song in question is Men at Work's "Down Under". The cartridge is an Ortofon Cadenza Bronze retipped by Soundsmith. I went through a lot of the protocols for abating annoying sibilance.
1.My anti skate was not optimally set so I thought and I adjusted to less using a dead spot on a test record. I know some people don't agree with this. I tried Soundsmiths method but until I see a video I won't understand it.
2. I adjusted my VTA to at least 20 degrees. I realized it was off. It was set at 12-15 degrees. I know the Shibata stylus is sensitive to VTA.
3. I checked the VTF and it was set at the manufacturers suggestion at 2.5 grams. Which is dead in the middle of 2.3 to 2.7. I adjusted to 2.62. A lot of people think the higher range is optimum.
3. I made sure my stylus was absolutely clean.
Guess what? After all this, the sibilance was less but still there. As a check I listened to the song in streaming and it was in the recording!!! However not as bad as my record before my TT adjustments. So I'm happy now my TT might sound better on other recordings. Anyway I hope my fellow members here have had some success on sibilance and maybe some will benefit from what I did.

Sorry to resurrect this thread, but tonight I am reminded of a particularly difficult album to track...without sibilance.

Norah Jones, "Not Too Late"

From the very first song, there is a lot of 'sss' to navigate.  This could be attributed to a 'hot' recording, but if you can get a phono cartridge dialed-in, it can sound wonderful.  For me, it required a combination of high-quality, low-mass cantilever/stylus, along with very exact cartridge alignment (including VTA and azimuth) in order to get a satisfactory result with this album.

jdjohn, sibilance and miss tracking distortion are two separate problems.
Even the best, perfectly maintained systems can have recording induced sibilance. Miss tracking distortion certainly sounds terrible and can be do to bad styli and cartridges but it is not sibilance even though it makes you squint just as bad. The easiest response to sibilance is just to turn the volume down a little. This will not get rid of miss tracking.

Mijostyn, you cannot assess whether any speaker has a deliberate gundry dip incorporated into the crossover simply by measuring the response of the speaker, because there are natural dips that occur in association with a crossover from one Driver to another. So you can not know whether that is an incidental artifact of the crossover or a deliberate dip. Further, the very benefit of a loudness control is that by turning the control one way or the other you are adjusting the level of the compensation for the Fletcher Munson curve. Because the degree of loss of sensitivity to bass and treble frequencies relative to midrange varies with sound pressure levels, the adjustability of a loudness control affords much more flexibility  than incorporating a fixed Gundry dip into the crossover network. Did you actually inquire whether  Wilson incorporates a gundry  dip into their crossover networks?

Mc low gain  is always much longer settling time. even just changing the stylus only.

and the cable burn in etc is much more difficult due to low gain. also if it's hot sounding.. check the capacitance and loading make sure it's in range. nothing to it really.. patience.

@lewm , the dip is there. Now, you could argue as to whether or not it was intentional. Would Wilson do something that was not intentional? 
Most loudness controls I am familiar with are just on/off switches with only one curve. It would be very complicated and expensive to rig an analog variable control. My TacT is the only unit I know of that has dynamic loudness compensation. It hops from one curved to the next with output level. It happens automatically. I love it. But, no other digital preamp with the power do do this has the programming. I suspect (but do not know for a fact) that Bozevick had a patent or copywrite on this programming. Others will institute it in time. 
By the way, there is no one Fletchur-Munson curve. It is a continuum that is outlined by a set of curves that vary with sound pressure levels. Your ears do not hop from one curve to the next.
