AT-ART9 cartridge on Marantz TT-15s1 - I don't think I'm getting the performance I should


Some time ago, frustrated with what was likely cartridge alignment issues coupled with worn LPs, I upgraded my cart and sold my VPI Scout turntable and now have an AT-ART9 on a Marantz TT-15s1.  That turntable was recommended to me because of its relative simplicity in cartridge alignment.  I've been really enjoying the fullness and clarity of the AT-ART9 on some LPs.  By "some" I've found that I mean records without obvious wear and that are cut on the quiet side. 

What's bugging me is that I feel l am getting far from the best out of this cart.  I have read that it is REALLY finicky to dial in for best tracking results, and my cart doesn't appear to be tracking a lot of records well at all.   I started buying a lot of vintage sealed records to eliminate groove damage from being the issue.  But I've noticed that almost every album that's cut on the "hot" side plagues me with distortion that gets worse as the stylus gets nearer to the inner grooves.   For example, I've played a lot of '80s hard rock and metal, and I can almost count on any album from that era cut on the Atlantic label in these subgenres to give me distortion that's clearly due to mistracking. 

What may set me apart from others on this forum is that I don't have buddies with comparable systems in driving distance from me where I can bring my records to hear on their systems, so I really have absolutely no basis for comparison.  I have just read people say that they have never heard IGD with this cart, whereas I hear it on many 75% of my LPs.  I don't have any problems with known audiophile pressings though, like new stuff cut by Chris Bellman, Kevin Gray, on the Classic Records label, etc. 

I used to have my cart professionally set up, but after finding that my dealer totally bungled the setup on my VPI the last time, I decided to learn how to do it myself.   I got myself several Stevenson protractors and a 3x magnifier so that I could see what I was doing, and it absolutely looks to me like I've got my cart aligned as perfectly as one can get it using the null points on the protractor.  

I *do* however think anti-skate is causing me problems with my configuration.  I did have it set too high and that absolutely caused me more distortion in the inner grooves as well as a large number of records "sticking" (i.e. repeating instead of skipping forward).   But even after adjusting this heavily, I still find that in the rare case that I have a used record that skips, the tonearm "sticks".   That, to me, suggests too much antiskate, but I have set the antiskate to be almost as minimal as possible from the best that I can tell. 

Absent of a local dealer that I've yet to find who I can trust to identify and fix this issue (especially since the nut used for setting antiskate on the Marantz is so loose that it would easily change while driving my TT back home), I'm at a loss having done everything I can do to possibly fix the problem. 

Based on what I'm saying here and your experiences, am I most likely missing out on the supreme tracking abilities of this cart, or is there just a lot of really bad pressings and damaged used vinyl out there?   And if it's the former as I suspect, is there anything about the Marantz's tone arm that suggests it's not up to the task of supporting this cart?

I didn't read every word but could your tracking force gauge be bad. You could try to float the arm and set counterweight to zero then set counterweight to 1.5 - 1.8 and see if you gauge is close. Sounds like it could be a bad cartridge. Could anti skate be broken? Set anti skate to zero or half of tracking force recommendation. Try just a basic protractor for your arm printed off vinyl engine. 
Have you tried turning off the anti-skate to see if that is the problem?  
Have you used a bubble level on the flat part of the tonearm headshell?  
The ART9 is sensitive to VTA.  
Level the platter with the bubble level and then check the level of the headshell when the cartridge is in the groove of an LP, obviously tracking force adjusted to account for the weight of the level. 
Once you level the headshell relative to the platter, you are at "0" and a great place to evaluate the cartridge's performance.  
Didn't you get a protractor with the turntable?  Use that one for now and check the alignment.  
If you have to adjust alignment then re-adjust VTF.  VTF for the ART9 (for me) was 1.85G.  
Sounds like something fundamentally off in the alignment.  Your tonearm is optimized for the ART9 and it is capable of sounding as smooth and clean as anything.  
The '9 does tend to sound warmer and bassier on belt drives and tables with acrylic platters (which are not good IMHO) .  However you have work to do before you get there.  
Thanks, avanti1960.  I've got anti-skate at a minimum based on the results from both the HiFi News and Analog Productions test LPs.  And you bet I've used a protractor and gone over the alignment probably 10 or 15 times at this point. 

I've read that VTA for the ART-9 is best at slightly tail-up from various sources.  If I read you correctly, you're suggesting to level it off?   

Anyway, a few posts ago I mentioned that I had solved the sound issue by using the Fozgometer and tilting the cartridge at an angle that really *shouldn't* be correct.   I played several records and they all tracked perfectly well, and I was paying REALLY close attention. 

But now already something seems wrong again.  I made NO changes whatsoever, and even though the IGD is still gone, I'm clearly getting distortion on clean records again, which is totally the sound of misalignment.  So I'm going to do a few more tests before I (hopefully) draw a conclusion.

Unfortunately, things are starting to point towards a damaged or defective cartridge.
Have you done the mirror test as described by Mijostyn? When you do, let us know your result. If, with the mirror test and the cartridge body visibly tilted in the headshell, the stylus tip is not sitting Square in the groove, then I would ignore the fozgometer completely. I would then reset azimuth so that the stylus sits Square in the groove regardless of anything else. Then see how it sounds. What the other guy was suggesting as regards VTA, is to Start with the head shell parallel to the LP surface and then move the pivot up or down to find your happy place. Other people with experience using the ART9 have already mentioned they prefer the pivot slightly up or down, can’t remember. But that is your choice ultimately. Any test LP that asks for the listener to look for a mono signal from a stereo cartridge in order to set azimuth is not doing it the right way.
If you're willing to drive 3-4 hours my dealer, Deja Vu Audio in Vienna VA are analog specialists they will set that table and cartridge up right. Also they are a  Clearaudio dealer, amongst other brands, and your table is made by Clearaudio.
