I have an old Sota Moonbeam turntable with a Grado Platinum cartridge and am getting 

a lot of vocal sibilance.  I don't hear it on any CD's.  It is worse on loud passages,

when it localizes to the speakers.  It happens on many different LPs.  What causes this?

  • You fail to mention what tonearm is in your system. It could be as simple as a mismatch between cart and arm.

    In my personal experience, excess sibilance is usually an issue with set-up. I would have my system checked by a turntable set-up expert, such as Michael Trei.

    • The tonearm is the stock one that comes with the turntable. — dcaliano January 20, 2013 8:43 p.m.

    • Just because it's the stock tonearm, doesn't mean it's not a potential mismatch with your cart if not set-up properly. If it has, from day one, had sibilance issues, that indicates the cart has never been properly installed — StevenStone January 21, 2013 6:12 p.m.

    • It could also mean an aging or even damaged stylus or cantilever. You didn't how long it's been in the system. — neilgader January 26, 2013 9:07 a.m.
