I saw some cartridge movies on Youtube made by Dutchfly.
AT440MLa
Goldring 1042
Grado Prestige Gold
Denon DL-160
I have a couple of questions about them: (to Dutchfly or others)
1. I hear you naming the frequencies but the tone I hear is much higher. Must I multiply it with 1000 or have you electronically raised the freq?
2. I saw that with curtain freq the cart is starting to shake, is this because of the compliance of the cart? AT 10cm/dyne, Denon 10, Goldring 16 and Grado 20.
The Denon doesn’t shake at all and the tone stays stable, medium mass arm of the Technics?

Interesting that the AT has a resonant frequency of ~8Hz in this arm- using an online calculator, and arm between 2.5g and 13g eff. mass would get this cart within the 8-12Hz frequency range.
This ranges to a little heavier than I would have expected, given the high compliance of this cartridge.
Also, the calculation for the Dynamic compliance give 20.8x10^-6 cm/dyne. The spec sheets give a value of 10 for the dynamic compliance, and 40 for the static.
Just thought I'd mention it.
