Sorry for long title but I wanted to post about this. I've been frustrated as of late. I've been through a VPI Classic and a handful of carts and I just couldn't get rid of this terrible sibilance and IGD. I tried everything I could think of; less VTF, more VTF, azimuth adjustments, VTA adjustments, no anti skate, lots of anti skate etc etc. Eventually I became fed up with everything and sold the lot. Then the bug bit again and I decided I would give this one more crack. I grabbed a PLX-1000 on a stupid deal (40% off RRP) and used a few contacts to get a Benz Ace SL and Musical Surroundings Phonomena II+ at good prices. I also grabbed a Feickert protractor on the used market to make sure set up was bang on. I set everything up, played some records and BOOM! Sibilance again. I was also finding that the stylus was violently skipping the lead-in groove when I dropped it in. I was gobsmacked. I was sure the Fine Line stylus on the Benz would solve these problems but no go. I had set my anti skate to 2 on the dial as I was tracking at 2g so I was pretty sure it was correct and I didn't think there was a reliable way to check it. Just set and forget. Then I found a post on the SH forums about setting anti skate using the Soundsmith method. This allowed me to set anti skate by dropping the stylus in a blank part of the record (while spinning) and seeing which way it skated. Turns out I didn't have nearly enough anti skating. I had to turn the dial to nearly 4.5 before the stylus slowly tracked towards the spindle. Doing this has completely eliminated any of the previous issues I had and the system now sounds absolutely fantastic. I highly suggest everyone give this a go. You may find it doesn't work for you and if you don't have similar problems it might not fix anything but it's worth a shot to see if it makes any improvement. https://www.sound-smith.com/faq/how-do-i-adjust-anti-skating-my-cartridge Procedure: When you have it adjusted right, the arm will track on the SURFACE of the record (not in the groove) at the end of the record on the un-pressed flat space where the run-out groove is – it should track SLOWLY INWARDS toward the center at a MUCH SLOWER RATE than IF IT WERE ACTUALLY in the end groove. If you do that, then the best average Anti-Skating is set correctly.
