New VPI 3D Arm


At last I have the arm in place and set up - though I think the tweak adjustments are still far from done. I had in place a VPI 10.5i arm with a Benz LPS, on a Superscoutmaster/Rim Drive with Bearpaws in place of the original VPI mini feet. The rest of the system is an Ayre K1xe preamp with their phono board in place, an Ayre V1xe amp, and Vandersteen 5A speakers. I set the new 3D arm with a MINT protractor, and a Fozgometer. The arm was sent to me with a standard rear counterweight of 120 grams that included a Soundsmith Counterintuitive to ease the setup. How Nice I said to myself, however, Harry himself recommended a 200 gram counterweight because my cartridge was so heavy. The new weight was sent to me, without the Counterintuitive...when I inquired why not, it seems that the C/I wouldn't fit the larger, heavier counterweight that was needed for my cartridge. So..off I go to set up the new arm. Let me tell you the setup is the clunkiest, most time consuming, most exasperating work, I have ever tried. I just gave up after many hours, and contacted VPI to vent. Harry told me that if I oiled the inside grommets of the rear counterweight, it would move much easier/smoother....and so it did, however, I would grade it as a D+...better than the F before, but not good at all. When moving the counterweight it still gripped the tonearm make any kind of precise movement a matter of luck. Harry told me he was working on (almost done - ready to market in about a month) a new counterweight system that would permit easy fine tuning with no problems. I suggest anyone who is about to get a 3D arm to insist that the new counterweight be included with your purchase. Harry promised me one of these, and I will report on these pages when I get it and how well it works. Anyway...probably most of you want to know how the new arm sounds. I must remind you that the arm is still new and really not tweaked to the nth degree. My first album told me immediately that this arm was completely different than the 10.5i (which I think is a great arm when set up correctly). The music from the speakers with this arm is completely relaxed....that hits you in face immediately. I'm not sure I can explain it further then "relaxed". When playing Paul Simon's new album with the 10.5i, I had to strain to hear the words to the tunes....which was odd to me since Paul's prowess as a poet is hard to criticize. With the 3D arm, the words and Paul's talent is completely exposed. Instruments are much more rounded and in their own space - individually...as in real instruments playing. Right now, I would describe the low end as a bit weak, however, the cables are not broken in yet, and back end of the arm just may be too high. After all of the aggravation and hours of setup, I'm not ready to adjust anything yet...just want to rediscover my vinyl. This is a work in process, and I will post again.

So why should a 3D composited form perform better than a cast or machined version made from the same material? After all, there is no crystalline structure at the molecular level. Such material is amorphous.

Seems gimmicky, as in we do to because we can not be uses it makes scientific sense.

And this from a very happy Aries2/10.5 owner.

A printed arm would not be inherently better; it could be cheaper to make if the production run is quite small (no need to machine the tools needed to cast the arm).

If the arm were made with some kind of complex internal structure to increase rigidity, it is possible to print an arm that would be impossible to make by other processes, but, I don't believe the VPI arm is made that way (at least VPI has not been touting such an advanced development). It appears to be a somewhat conventional arm made from epoxy resin.
Another happy VPI customer here and I'd like to extend my thanks to Mat publicly as he deserves. Mine was an issue with an SDS unit not a 3D arm, but I found all the VPI bashing in this thread quite upsetting so I decided to post here.

I find it absolutely incredible that Mat finds the time to personally answer all these emails and is trying his best to rectify the problems while having a company to run. I do understand the frustration expressed in some of the posts, but VPI products have always been superb and are undeniably great value given their price despite the wrinkles the company is experiencing due to its dynamic growth. I will continue to support VPI for years to come for the joy their products have given me, their reliability, and the company's ultimate dedication to their customers.

Since Mat took over the management of VPI I have personally seen only positive changes, and I have no doubt that it will only get better. Thank you, Mat, for your dedication, incredible customer service, hard work, and the passion to continue carrying on VPI's legacy.

Well, I started to set up my 3D tonearm and ran into a snag. After installing the new tonearm bearing and tonearm rest, I found that the azimuth weight on the left side of the arm hits the VTA tower- there is not enough clearance between the tonearm and VTA tower for the tonearm to move!

Very frustrating!

I sent Mat an email. In the meantime I found that the VPI website shows a BLACK colored VTA tower with substantially more room between the 3D tonearm and VTA tower. This is a different design. My VTA tower and assembly is the silver color, so I believe the fix for this is getting the black tower (hopefully).

Stringreen, did you have this challenge with your 3D arm setup?
