Killing sibilance distortion - VPI & Jubilee


Hello,

Along with what others have posted in the recent past, I also have a long running case of nasty distortion on sibilants with my vinyl playback. It is worse in the inner grooves.

To build on some other recent threads about this topic, I ordered a MFSL that is supposed to be a good test for mistracking. I have made a recording clip of my playback playing some of the last track on Side 2.

I have the recording on this link:

Playback Recording

If you take a look at that, we can all be on the same page with what exactly is going on.

The setup is a VPI Scoutmaster table, JMW9 sig arm, Ortofon Jubilee cartridge. The table is leveled on a Salamander Archetype rack. VTA is set with the arm parallel. VTF is set to 2.4g. Alignment is setup with the MINT arc protractor, 10x magnification. The VPI mechanical Anti-Skate is being used, with the lighter rubber washers. Azimuth is level by means of the "VPI straw trick" (a straw in a groove on the headshell).

Is there anyone that can point me in the right direction to fix that sibilance distortion you're hearing on the recording?

I've tried quite a few things, including different cartridges, and VTF, VTA and antiskate settings, but the sibilance is always there.

Here are some photos of my setup:

I started reading through your thread and this last post prompted me to reply. I also own and use a 33PTG cartridge and I've found it to be an amazing tracker. It may not have quite the treble response and clarity or the better tonal balance and bass "slam" of the other cartridge I have setup, a Dynavector DV20XL, but the 33PTG almost never reveals sibilance distortion (if I'm using that term correctly) that I occassionally hear with the 20XL. I actually use the 33PTG to verify whether the distortion I hear from the 20XL is caused by a damaged used LP or is an alignment or tracking problem. (I have identical turntables setup so can easily compare specific components such as cartridges, phono stages, cables, etc.)

I'll be setting up a new turntable and tone arm sometime in the near future (when they arrive) and so will have an opportunity to see if a tone arm upgrade minimizes or eliminates the occassional sibilance distortion I find with the 20XL. I'll try and remember to post my findings.

Hi, Goatwuss, the turntables are mmf-7 with the aluminum Pro-Ject 9 arm. Nothing fancy but they work. The DV-20XL rarely has problems tracking but there are a few recordings that seem to give the cartridge a bit of trouble. The AT33PTG just plays on through. It isn't quite the cartridge that the 20XL is so I don't listen to the 33PTG as often.
