Tone arm resonance and cartridge compliance: How do they interact??

@lewm @cleeds 

Gents, my diatribes were only in regard to the OPs question regarding resonance. Obviously adding mass further out from the fulcrum is the most effective use of mass, but (as I described) is problematic for mechanical reasons and is not the most effective method of reducing resonance amplitude. Calculating the change in resonance magnitude will require additional information not provided.

Now if, as lewm proposed, we are allowing the alteration of other factors including "damping, stiffness, materials used" then all bets are off. I hadn't realized that we were discussing a tonearm with an infinite k value. 😁

TL;DR ...

One point I’d make is that the numbers are a good staring point, but will take you only so far. I’d give serious credence to "tribal knowledge", trying the combination out, as well as the advice of a trusted dealer.

I took the compliance calculator off our website because I was seeing too many people treating it as gospel instead of as a guideline.

A customer brought over a Van den Hul cartridge to test with a Kuzma 4Point (11"). Frankly (from the compliance and tracking force recommendation), I didn’t think this would be a good match, but that’s why you try things.

I documented that session over here https://galibierdesign.com/van-den-hul-demo/
I suspect the Kuzma’s phenomenally, low friction bearing plays a strong part in this, as it’s a wonderful combination.

Haven't seen a telegram in maybe 50 years except while watching an old movie on TCM.
