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.

Those who read these pages are probably interested in getting that last degree of perfection out of their setup. In mounting my Benz, I took the suggestion of Fremer at the Analogue Planet and tried for a 92 degree SRA with the stylus set up as pictured in his article. This required the arm to be absurdly high in back, so I contacted VPI, Soundsmith, and others regarding the SRA issue. Peter from Soundsmith said that article is misleading because the way diamonds are cut can dramatically change the way they act...that is, the stylus may look leaning forward or back, but still be 92 degrees at the tip depending on the cut. Peter said that he has styli on his cartridges that are the same as my Benz....one should raise the back of the arm to horizontal, then play with it up or down for your own perfection. Now....on to what the arm sounds like... With the arm lowered in the back to horizontal, the low end is fat, faithful, and satisfying. The mids as I said before are clear with each instrument in its own space...round and delicious. Massed vocals sound like massed vocals...not just a wall of sound. I should also mention that the platter on my VPI is the ceramic one that's used on the VPI direct drive.
Thanks for the initial 3D review, Stringreen.

Overall, would you say you prefer the 3D over the JMW 10.5i? or is it still too early to call?

p.s. I also have the ceramic platter with groove + rim drive.
As soon as the stylus hit the groove - even before the music started on the first album, I knew this arm was better. The arm does not seek to find the lead in groove...it just lands there with no jiggling. The 10.5 was quiet, but the 3D sounds almost CD-like. It is very fast, with an enormous soundstage with depth and width bigger than the 10.5. It tracks the most difficult passages with total ease....sss's are absolutely clean with no sh,sh, or spitting. Each instrument has its own space and posses a roundness ....but the most important for me characteristic is its total sense of ease....like real music. You have the option of Nordost or Discovery wire....Harry told me the Discovery wire is HIS choice, so I had mine wired with it, and I'm not at all disappointed. My arm is wired balanced (XLR connections) and is DEAD quiet.
