Linn Forums

The cartridge weight range of the Ekos-arms are given as 4-9 grams. There is no problem to balance my Benz Ruby 2 with a weight of 9.6 grams and the counterweight can be located even 3-4 mm away from the pivot point of the arm.
The weight is of course dependent of the placement of the cartridge in the shell but anyhow I am quite sure the arm could take more than 9 g.

Why has Linn choosed this limitation, i.e. max 9 g?

Hi

I cannot answer your question for sure but it is probably something to do with the considered ideal position range of the counterweight to give the best sound. Usually, the nearer the pivot point, the better.

Since you have a heavier cartridge (and if you have a stylus downforce gauge) you could try dialling out some downforce and moving the counterweight forward until you get to the correct downforce. You may prefer the sound! Whatever happens, it will sound different. This will also be due to the reduction of the sprung downforce efferct.

Best wishes, HM

Hi HM.

I have thought of that as well. I have bought an even heavier cartridge and if I cannot balance it I will use my electronic gauge and set the downforce wheel to zero, as you suggest.

But I don't understand why it should sound better with the counterweight nearer to the pivot. Can you?

Hi Hallgrim,

if you move the counter weight away from the pivot you increase the dyn. eff. mass of the arm. The arm reacts slower than before.

cheers

Some people prefer the sound with the tracking dial set to 0 and the tracking weight applied with only the main counterweight,

I am aware of that, Thorsten, and to maintain the balance you need a heavier counterweight to compensate for the shorter arm. And you are right: The moment of inertia "I" = MxRxR and that means that obviously "I" will be larger with a long arm and light counterweight than a shorter arm and a heavier counterweight.

So Linn:

PLEASE MAKE A HEAVIER COUNTERWEIGHT FOR MY EKOS SE

Hallgrim

I could not of put it better myself.....

Yes Linn, whatever Hallgrim says.... but for my Ekos 2

But Hallgrim, its an elaborate rouse to make you buy a Linn cartridge. You need an Akiva, didn't you know that?

HM (who prefers the spring downforce on the Ekos SE!)

OK, but still with an Akiva the counterweight should be heavier for minimum moment of inertia



HB (who likes the Benz-presentation)

Nah, the SE counterweight is optimised for the new Akiva SE weight!
