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.

I finally installed my cartridge onto the 3D tonearm for my Super Scoutmaster Rim Drive Reference table with Classic platter. I drove to VPI (about an hour from my home) and they helped get the right counterweight and made a few preliminary adjustments to the arm (Thank you Leo!!) as I was shipped a 180 gram weight for the JMW metal arm included with the 3D arm which does not fit on the 3D arm. They also changed the mounting base for my VTA tower, as the 3D arm was hitting the side of the tower on the original baseplate. The 180 gram weight is way too heavy for the Titan-i cartridge which was previously recommended on the VPI website for this cartridge. I believe I ended up with a 140 gram weight with a small fine counterweight adjustment attached.

The CounterIntuitive that came with the 3D arm was too tight on the counterweight and very difficult to adjust even after putting on some oil, so I did away with it, which made adjusting VTF & azimuth easier. I also started using the SoundSmith cartridge screws (aluminum) but found that the high profile made it more difficult to adjust azimuth, so I ended up using regular screws with tiny washers which came with the SoundSmith screws. All in all I spent about 10 hours installing the cartridge, as the Mint LP protractor is extremely precise with very thin lines.

I used the Mint LP protractor for this arm, as I had also used it for the 10.5i tonearm. I used a Fozgometer, a CartridgeMan digital force gauge and digital level, a magnifying glass and a good hand-held LED light (Larry brand).

I will make a separate review of the 3D arm, but my initial listening shows that this arm brings more music, more information, is tonally more accurate, and is more detached from the speakers with more impact and better attack, sustain, and decay.

I want to thank Mat and Harry at VPI for their help, support, and hospitality. They were truly great to deal with and helped correct the glitches with the 3D arm. I was also invited to Harry's house to listen to his various listening rooms with different systems- I thought I was in audio heaven- it was great to listen and spend some time there while my tonearm and turntable were being adjusted and corrected. Harry is truly a music lover and audiophile of the highest order. Thank you again Harry & Mat!!! You guys rock!!!
Okonrad.....I also have a 3D, but was told that my arm has the "old" side weights...that there are new larger side weights now, however the tower has to be changed to a new black colored one to accommodate the larger space so that the new weight doesn't bump into it. Does your Atlas play well? ...don't know if I should do the Atlas or Etna....
Does it ever. I have a Kleos mono too, but the Atlas is very addictive. Been listening to the Cassandra Wilson Miles vinyl issue that Blue Note just release. Holy s&$?!

I have the larger counterweights that don't take the counterintuitive. They are hard to work with but I have alot of experience in setting up tonearms, so it was fine. Now that everything is dialed in I don't want to change anything.
I did hear the comparison between the 3D arm and the regular arm(on Mikey's site?), and was suprised at how many chose the regular arm. I don't know the cost difference, but thought it to be a definite improvement.
