System resonance.. How crucial is it?

[deniall]

Been reading a bit about system resonance recently on vinyl engine and I have been using the resonance calculator to figure out if different arms and carts match well. One thing that has puzzled me is that carts that people usually recommend for certain arms/tables seem to be a horrible match. I was even looking at show reports and I typed in some of the cart/arm combos that manufacturers were using to demonstrate their gear and they were in the 14-15Hz range. Not even close to optimal according to the folks on vinyl engine.

So my question is, how important is this? I am yet to find an arm that matches well with the Denon 103/103R and I'm starting to think maybe it's not such a big deal.

good question !

 

IMO, lots of factors and resonance freq is just one, perhaps not most critical 

[deniall]

Take this for example. Avid Ingenium with Pro-Ject 9cc arm and Denon DL-A100 cart. Has a resonant frequency of nearly 17Hz (optimal being 8-12Hz). What other factors come into play to make this combo work?

I recently played with different armtubes on my tonearm, affecting a change from 14Hz to 10Hz. Significant difference. Definitely worth doing the math in my opinion.

Running about 10 Hz myself, spot on Chill, high mass seems to be the direction at least form my efforts. Fluid Dynamics will only get me down any further.

The Q of the resonance is an important factor.This should be low to avoid the situation of a continuously excited L.F. vibration interfering with the reproduction.In other words,the arm/cartridge damping should be such as to prevent oscillation occurring but not  effect tracking.
