The reason I asked about the actual loading on MC is because I was wondering how they got the extra 11db for the MC input. If they used low gain transformers then the actual load would be 47k/turns ratio (of the transformer )squared - which would result in a load seen by the MC cartridge somewhere between 3500 - 5000 ohms.
According to Steophile review of the Cat SL1 Renaissance MC unloaded measured 3560 ohms.
So it is possble your load is between 3 & 5kohms.
Jonathan Carr the designer of your cartridge says that loading does not affect the cartridge itself with modern MC designs, but what loading can do is dampen any ultrasonics that might affect the phono stage ( solid state devices can have low overload margins at very high frequencies, whereas tube designs less so ). Thats why he specs out loading range up to 47k.
In my view if you can run MC's into higher impedances without upsetting the phono its a good thing. Klyne has done this for years, they use higher loading combined with very high frequency contouring to tame any ultrasonic nasties.. you are hearing the benefit of "unloading" your cartridge.
