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

Thanks for lot of inputs and data points for me to work on. 47K for set up I am trying is definitely way too thin sounding. 40 ohm is a tad fat. 400 ohms leans towards lower side of lean, closer to flater, very tight bass but little hot on high freq still. Which means 100, 150, 200 ohm might work for the set up. Although I will try out 1000 ohm just for another data point.

Thanks.

Nsgarch- I thank you for the guidelines you have provided, that would sure help out me and other in simialr situations. May be I missed it but what was the rational behind the 25 times internal impedance rule? In any case the 25 time rule has been proving itself in my set up.
