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 Nilthepill  (Reviews | Threads | Answers | This Thread) 04-03-06
