You should determine if the cartridge is a good match for the arm. It may have harmonic mismatches that create sibilance and this is something I have had a great deal of exposure to this last year or so.....You need to tell us what you hear, what you own and what you have done to try to get it better.
Then we can point you in some productive directions.

...by a static like noise during louder sounds. This is because the stylus has "caught air" over the hills in the groove and carved out little dents where it careened into the wall again.-Bry

Usually misalignment. If there's not enough tracking (downward) force, or the anti-stake is way off (too much inward or outward force) then the stylus will lift off when the forces on it get too great. Although less common, it also can be caused by an untamed resonance in the cartridge/headshell/tonearm combination.Another cause is a damaged/worn stylus that no longer rides like a smooth bearing on the groove wall. A worn stylus develops flat spots that tend to alternate between contacting at the leading and trailing edges of the flat area during loud passages.
Anyway, all of this tends to turn records into large drink coasters or frisbees.

You'd be surprised how far such discs will fly from my 6th floor balcony. And when you get bored of that, warming them under the grill makes them flexible enough to do all kinds of sculpture.

often too low a vtf and sometimes due to the LP (such as Telarc 1812). sometimes, skating is off.unless you are setting up a new cart or have bumped or harmed your table, it should not start suddenly. or if your cart is bad.
Too low VTF can cause mistracking. Another cause can be when the cantilever damping material dries out and becomes stiff.All cartridges have tracking limitations based on their design and some LPs have grooves cut so hot that some cartridges will not be able to track them properly.
There are a number of causes for mistracking, but once it occurs, it usually results in permanent damage to the record groove.
Good luck,

My Grado has inner tracking distortion on my Rega and had severe sibilance with the Rega, the the SME's (without silicone dampening, and with my Kenwood tonearm.These same records play fine with the Grado in my Magnepan Unitrac, the SME's with dampening, or with the Technics arm.
Also, they play unaffected by the Denon DL 103R.
I just think you have to sort through a lot of set up issues before you can categorically say a groove is permanently damaged. It has not been so in my case.
They don't sound anything alike.I have my share of used records that have exactly the damage John described, a static-like burst at dynamic peaks. If I switch to another copy of the same record and it plays cleanly through the same passages, on the same rig, it seems clear that one copy was damaged while the other isn't.
Of course this damage is more likely to occur on difficult-to-track inner grooves, so IGD or excessive sibilance may indeed precede actual mistracking damage. But those aren't the sounds of the actual damage and they aren't necessarily related. If properly set up, my ZYX's never display any significant IGD or sibilance problems. Yet they are capable of mistracking and causing damage on certain rare and very dynamic passages.
One possible source of confusion is this: a badly mistracking stylus sounds exactly like the damage *caused* by previous plays with a badly mistracking stylus. If two copies of the same record have those static-like bursts, the present rig may indeed be to blame. If three copies have that sound, the present rig is very probably to blame.

A mistracking stylus is actually swinging wildly about in the groove with all kinds of additional friction added (sort of like when you spin a wagon wheel too fast and it wobbles to a quick stop). When you play the damaged record back on a working rig, you track the wave properly, but with all kinds of added bumps from the damage. I would tend to think the latter would be much less offensive sounding.

It may depend on the cartridge.My ZYX UNIverse can lose contact with the groovewall on one particular record (Curzon/Liszt/Speakers Corner-Decca SXL 6076). That produces the static-like burst we're familiar with, and it sounds exactly the same as records damaged by other rigs.
Now with this cartridge there is no audible distortion of any kind up until that moment. Except for that split second it plays as cleanly as it does on every other record.
Other cartridges might well act differently however, so I shouldn't deduce a general rule from the behavior of one cartridge.

Doug remember when I spoke to you about skitter. I thing sibilance is simply when the vtf at that frequency does not meet the vtf at other frequencies. So this is basically a supension anomaly and not true mistracking.I think we all agree that playing a record too lightly with vtf is a receipe for permanent damage. And that tracking too heavily may cause bad sound but possibly have less groove wall distortions.
I just wanted to point out to everyone that we must be completely clear about what is mistracking and what is audible distortion. The one may not be the other.
The groove damaged records I come across are blatently destroyed in all volume regions, quiet, medium and loud. I just throw these out, sometimes keeping the cover if it is minty.
I worry that many of the inmates here really cannot distinguish between distortion caused by sibilance or inner groove dynamics and that caused by gross mistracking. I do not want them throwing out a perfectly good LP that simply needed a better cartridge arm match.

...that not all cartridges can track the most aggressively cut records. You can use a test record to see what your rig will do.-Bry
even jumping off the groove on loudest grooves. Voices sound like FM mistuning while driving in the car. Bad for the record grooves.

you seem to have very large area of knowledge with better tt than my old Linn Basik kit table.
is that I think I need a new cartridge and am considering the Linn Akiva. I really like my local Linn dealer. However, I have heard both rave reviews and claims that it doesn't track well, so I want to know what to listen for. It's a lot more money than I've ever spent on a cartridge, so I want to be sure it's a good product.
With regard to my system, I had some really good advice from knowledgeable people. I don't know as much as I should about turntables (which is not good, since my tt is my primary source), but I'm trying to learn. I have had the benefit of a good dealer who has set the tt up well as far as I can tell, so I never had to worry about it, but I am trying to learn setup myself now.
I have to revise my AA system description: I now have open baffle Phy-HP speakers (no crossover!!!) that sound great. I made them myself (not hard).
