TriPlanar tonearm outward skating issue


Hi all,

I have been trying to research a solution to a recent issue with my TriPlanar VII UII tonearm that I bought  a couple years back.

The tonearm seems to want to skate outwards, even with zero anti skate applied and the weight removed from the little anti skate arm. It is evident at various settings of VTF, VTA, etc. The platter is very level and everything seems to be aligned OK. This outward skating force is very light in the outer grooves and becomes stronger as the cartridge gets closer to the end of a side. In fact, as it traces the lead-out grooves at the end of a side, the tonearm sometimes thrusts outwards across those grooves back into the last track. Very scary!

A visual check of the cantilever azimuth seems to confirm an outward pressure from the tonearm since the cantilever is leaning with the stylus end closer to the spindle.

I can’t seem to find any information online about this phenomenon.

Any insights and recommendations would appreciated.

@atmasphere : I'm not insulting " others " as you said. I'm only telling that something is wrong down there and what is wrong is coming for a faulty design.

So maybe according to you if I give my opinion of  something anormal in an audio item behavior then I'm insulting the manufacturer. That's you not me.

Enough.

I think we can all agree that all arms have compromises; nothing is perfect. Having recorded and produced LPs and also having mastered them myself though, I can safely say that amongst arms its price and those costing quite a bit more,  the Triplanar offers the least compromise.

You have boasted about your arm but but it is conspicuously absent.   
Raul,

I think it's time for you to let this topic go, and to accept (as Ralph and I have written) that there is no perfect tonearm.  More importantly, the best tonearm for one person may not be suitable for another person. 

We interact with machines in a very personal way.  Every individual hears differently, so a design decision (design decisions are compromises in many cases) may be sonically acceptable to one person, but not to another.

I don't want to pollute this thread with too many of my own rants, but if anyone is interested, I posted on the topic of "the best tonearm" to my blog (https://galibierdesign.com/best-tonearm-01/ ).

I enjoyed our time we spent together when you were traveling across the country with your Essential preamp.  We will always have our philosophical differences, but in person, you are a 1st class gentleman.

Balancing things out, I never thought I'd bond with Lewm in person, but I had the opportunity to spend time with him and we've gotten along famously.  Sometimes the person doesn't translate from the written word (nothing new here).

I'd like to see this gentleman carry over to your online personae, as the individuals who find you abrasive and pedantic are doing so for a reason.

You have a wealth of knowledge to offer this community, but your "virtuous sonic warrior" approach ("my way or the highway") offends many individuals. 

Of course, free advice is worth exactly what you pay for it ;-)  Finally, a disclaimer:  my Spanish is much worse than your English.

Cheers,
Thom @ Galiber Design
One way in which some designers avoid the issue with the TP, that is the source of so much disagreement here between Raul and the world, is to route the wires so that they exit the arm wand just at or just before or just after the pivot. VPI and Basis tonearms adopt that style.  In so doing, the wires never have to traverse a right angle bend within the tonearm structure, which is the case with the TP.  However, the VPI/Basis (and Reed, I think) designs incur a penalty for choosing to externalize the wires at the arm wand; the wires asymmetrically affect the net friction in the horizontal plane, however tiny the added force may be.  In fact, VPI for years let that drag force serve as an anti-skate force. Herb Papier was no dummy; I am sure he was well aware of the problems related to routing of the wires, and he made the choice he made for a reason, probably to avoid the potential for the externalized loop of tonearm wires to affect the freedom of the horizontal bearing. This is just to point out that all design choices have their unique pluses and minuses.  Semantically, there is a big difference between "faulty design" and "design flaw".  The way I see it, the TP designer made a choice that can cause a problem if the end user is not careful or aware.
