VPI tone arm question.

Mjm, I own a tricked-out Classic basic plinth with a Classic 3 uni-pivot tone arm and base. When I first bought the Classic 1, I had a lot of difficulty matching a cartridge. No point in rehashing all of that now. If anyone is interested, they can pull my old threads.

It is worth mentioning, however, that IME two cartridge brands DO work well with the VPI JMW uni-pivot arm, namely the Sound-Smith VPI Zephyr and the Lyra Delos and Kleos. I used to own the Lyra Delos and give it top grades. I moved up to the Kleos, and I think it sounds even better.

I surmise that most of the other Sound-Smith cartridges will do just fine with the JMW uni-pivot. If one has any questions, they can call either Mike or Jack at VPI, or Peter Ledermann at Sound-Smith.

The Zephyr is my back-up carty when the Kleos goes in for service. Which raises an interesting point. I sent my Kleos to Andy Kim, the owner of the Needle Clinic, located in Washington State, for a check-up. Andy has garnered many compliments on A'gon.

I haven't gotten the Kleos back yet, it's in the mail. But all Andy had to do was clean and polish it. I was quite surprised because the stylus had at least 1500 hours of use on it. I pushed back and asked Andy how much life was left on the stylus and if he saw evidence of uneven wear. Andy reported at least 90 percent life left; no evidence of uneven wear.

To Kleos owners out there, or maybe Jonathan Carr, does this make sense?? If so, that says quite a lot for the Kleos, aside from its great sound.

Cheers.

No simple answer other than to research the cartridge in question. Cartridges perform best when mated with a suitable tonearm whether it be effective mass or bearing design. Some high compliance cartridges perform best in robust arms with fixed bearings.

At first I was reluctant to get a Classic One because the uni-pivot made me nervous. After setting it up with a Lyra Delos I wasn't all that impressed until I started adjusting that big 'ole azimuth ring. After I got the azimuth set right I was amazed at how every thing snapped into focus.

I use the screw down clamp on all my Lp's and the arm is rock solid, no rocking back and forth, tracking is excellent.

To answer Bifwynnes question, check the cartridge manufacturers specs. Not all specify what type of arm to use but Lyra at least recommends a high quality uni-pivot or linear arm.

Brf ... how is one to know the difference?

Some cartridges perform better with gimbaled bearings over unipivots and vise versa.

Good question Mr. M. I had the same question. Looking forward to an answer. I own a tricked-out Classic 2.5 (basic Classic plinth, with Classic 3 uni-pivot tonearm and base). I suspect that the pluses and minuses between the 2 arms offset each other.

Sorry about the double posts of my question. Did not realize it takes Audiogon longer to post a thread over the weekend.
