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.

Are you SURE is sibilance?  You haven't described the rest of your system.

There are a LOT of sources for annoying HF.  Speaker breakup, a crossover component gone bad, a tweeter issue, a metal driver starting to flex. 

Amp, preamp and phono stages can be sources of sibilance.  Lot 'o things can push electronics in the wrong direction.  Sometimes computers, their power supplies or switching power supplies can inject noise into the signal that can manifest themselves into HF noise.   

You might have addressed the phono source side, but there are a lot of other components that could be contributing.
