Sibilance issues

[jimwise68]

I have been having sibilance issues with my GL75. All standard, it was my dad's and I resurrected it. Just changed the V Blocks to new ones (replaced them a few years ago) but the tonearm still has some wiggle movement... is that normal?

I replaced my headshell,cartridge and stylus for a lightweight top screwing one with an Ortofon 2m Red. It sounds better but still has a bit of sibilance and some records seem a bit harsh in the higher registers.

I have used the protractor from here, and also a plastic protractor and VTA gauge to set up the stylus and it is greatly reduced but still there.

What am I missing or am I just chasing my tail?

Is the cartridge new? If so then it may just need some hours on it to loosen up

[jimwise68]

yes it is new. Didnt think of that 

Any excuse to play some more records then

Capacitance loading?

Tonearm wiggle is normal, nothing to stop it.  I mean when handling it, obvs not when playing a record.  I have an om10 with a reloop stylus tracking at 3g which sounds pretty ok.  The diamond when new is not really polished and sounds a bit 'rough' to start with.  I always play cheap old discs when starting out with a new cheap stylus (charity shops were very good for this).  If it were a posher diamond then a good polish from the start can be assumed but the red is equivalent to the om10 (bonded elip.) so entry level grade.

Hi, The Lenco arm is heavy & needs a low compliance cart to work at its best. The Red is not a good match for the arm as it has a high-ish compliance at 20. You need a cart with a compliance of between 10 to 15 x 10-6cm/Dyne.

Best bang for buck is a S/H Denon DL-109 cart with new Elliptical stylus, you will not believe the S/Q difference you will get.
