Sorry on typos, its VTF and 1.950 - 1.975 g in first paragraph.
Help me not let this happen again

The above link shows photos show a slanted cantilever on my Dyna XV-1s. VFT was 1.950-19.75g, SRA was 91.5 degrees, azimuth was spot on and AS was set as minimal (probably 25% of total AS possible on TW 10.5 arm). Associated equipment was a TW Acustic AC table and TW 10.5 arm. The table is perfectly level by multiple spirit measurements. Tonearm bearings seem to check out with a 'float' test of the tonearm.
Absolutely no damage occurred to the cantilever. System is in a dedicated room with kids in college and a wife that HATES my room and stays out. No mishap by myself occurred either.
I have had the cart for around 4 years and probably have between 1500-2000 hours on it. Over the last month I noticed image smearing and 'wandering' within the soundstage, lack of air, and increased sibilance. I started trouble shooting the issue and started at the cart. I was shocked when I noticed the cantilever slanted slightly to the right (toward the outer edge of the platter/LP). It was fixed there and didn't change while playing an LP.
My only thought was that I dialed in anti skate by ear and loved the sound compared to the increased anti skate demanded by a test disc. Could this be from insufficient anti skate? I was told by others that skate or anti skate forces wouldn't be strong enough to cause a cantilever to do this.
My fear is this: I was lucky enough that my cart dealer let me trade in my XV-1s for an XV-1t and gave me a solid deal. Now that I have my XV-1t I love it! I thought the XV-1s was great, but the XV-1t is phenomenal. But.......I don't want this to happen again!
Any ideas on the cause or other things to consider, please let me know. I appreciate any input. I just don't want this to happen over time to my new cart!

Thanks for the responses Peter and Ghosthouse. I have around 1500-2000 hours on it I'm guessing over a 4 year period. I clean it with a Onzow regularly and have never had a mishap (luckily) with the cart. I use a digital microscope or a 10x magnifier to assess stylus cleanliness and wear. I suppose it could be normal wear and tear on the suspension, but I just found it odd to be the horizontal suspension and not the vertical. The stylus is fixed slanted to the right whether playing or static on its armrest. As far as the XV-1t is concerned comparing it to the XV-1s, the XV-1t right out of the box and without any break-in was clearly superior in detail retrieval and sound staging. I have a post on Audioshark. Here's the link: http://audioshark.org/all-things-analog-21/dynavector-xv-1t-vs-xv-1s-5648.html#.VAm4Zksl6_0 |
Unfortunately if didn't take pics of the stylus before shipping it back as part of a trade in for my XV-1t. But looking at both the XV-1s and XV-1t stylus prior to shipping, they looked virtually identical and I could nit detect uneven wear in the XV-1s. But viridian, your analysis of uneven wear with inadequate anti-skate makes logical sense. |
