I need help diagnosing a sibilant problem on vinyl

Maybe you should check out my thread regarding Elys 2... Very sibilant on my system.

My problem may be a mismatch between cart and phonostage or the high gain of the Elys.

Are the Walls in your room close to the speakers on the sides? Without knowing your room description ..its hard to say. I get this in my room because its small..but I dampin about 20 degrees to the left and right of each speaker and this helps kill any ringing or harsh reflectance. Also, Cables are another thing to consider a bad cable can sound like u describe. I tend to take the easy route first and work up to the more complex fixes.Stylus tracking force and anti-skate are easy to check as well. Also,make sure the cartridge is not near any transformers from other equipment. I would check Grounding or consider running a ground from table to preamp. Table needs to be Perfectly level,check this at the plinth and the platter to make sure.Stylus or cartridge replacement might be in order if these others dont help.

I agree with all the above, and also add if the turntable itself is properly level on all planes and on a solid platform, and do use a record clamp to better couple the record to the platter.

Dougdeacon is it possible to get a list of those records that are hard to track.

Damaged or worn stylus. Harsh tubes?

How many hours do you have on the Elys?
