On tonearms that have removable headshells, the rubber washer that is in between the headshell and tonearm mount. Has anyone removed this? And does it change the sound any?. Linns philosophy was to let the vibrations go through the arm and dissipate through the tonearm base. Doesn't the rubber washer defeat this? |

I wouldn't put too much credit into anything LINN states,, |

I can't imagine you'll be disappointed. It looks like an excellent tonearm to me. Of course, the price is way more than I would be willing to pay. Hopefully, you've found a good deal. I doubt I could afford my SME V at its price today and the Kuzma is at least a thousand dollars more. If I were planning to spend that kind of money, I think I would go for the 12-inch version of the SME V. Of course, the SME V has always been my favorite tonearm since it was introduced. However, when you get into this category of tonearm, I don't think terms like "better" and "worse" really apply. There might be differences, but I don't think you can specify with certainty whether one arm is objectively better or worse than the other. Of course, the Kuzma 4-Point should definitely have slightly lower bearing friction than the SME V and it is nearly as long as the SME V-12. I was looking at the Kuzma website and I discovered what I believe to be an error in pivot-to-spindle distance for the Kuzma 4-Point. It is specified to be 264-mm at several places in their website, but it should be 265.37-mm for Löfgren's "A" alignment with null-point radii at 66-mm and 120.9-mm. Therefore, if you buy the tonearm, make sure you mount it for a pivot-to-spindle distance of 265.37-mm. This might be a little tricky because the arm base center is not coincident with the horizontal bearing center. Kuzma states the arm base should be mounted at 212-mm from the spindle. The problem that I see is whether mounting the arm base at 212-mm actually provides a pivot-to-spindle distance of 265.37-mm or whether you will need to mount the arm base at 213.37-mm to get the correct pivot-to-spindle distance. You definitely do not want to end up with a 264-mm pivot-to-spindle distance because the resulting alignment is absurd with gobs of inner groove distortion. Below are graphs of the two alignments. I have a feeling the 264-mm pivot-to-spindle distance is a typo because all other parameters seem to jive with Löfgren's "A" alignment. Good luck, John Elison |
