Helikon LOADING


Hi, I am really confused as to what is the right loading for this cartridge. The info that came with cartridge recommends 100 ohms to 47 K ohms. The inernal resistance is 5.5 ohms. This is quite a big range to decipher the 'correct' loading or 'equalization'(my analogy)and also tough to find the right phono that matches with unknown loading. I am auditioning few phonos at present and want to slect the right combination.

Also I want to have phono that is future proof, that is if I explore in multiple different cartridges, the phono amp is/will be compatible with these Carts. I read form past threads that general guideline is 25 times its internal impedance. How hard and fast this rule is?

So what is YOUR HELIKON LOADING? and how did you decide this value?

thx,

Nil

Years ago, all Lyra's were made for 47k, but only a few Phono Stages made that, so the manual changed the loading recommendations. I think, it is System dependent, too. When you have an adjustable one, you can check it out, from from setting you will loose high frequency information. I use most of the time 47k with a Klyne Phono Stage and it's own Filter settings, but there is not only 1 right value I guess.
I think, most of us are on the right track, Raul with his opinion and Gmorris with his explanations. When the wire in the arm is silver or copper, you can choose different loads, next is the wire from the termination box to the preamp, same story. I agree, that you can go the one and only way with the manuf. recommendation, but do you think, that all of them use a 1.class phono preamp? Or step ups? Or tubes? Or transistor? Even the tonearm material has different damping influences ....
