Raul, IF you have a good turntable and the arm you have attached to it is properly matched to the type of turntable you have selected, even though the arm and turntable are not of the highest quality, then I would agree with you that changing the cartridge would give you the most apparent change in the system.
However, for some one with a turntable/arm/cartridge who wants to improve what they are hearing its not that simple. Tonearms and turntables are not all interchangeable - the design criteria of each narrows down the possible choices. Some arms work better on suspended tables, some better of unsuspended tables. Of the tonearms that can be used on suspended tables one has to be sure that the weight of the arm is within the capacity of the spring suspension otherwise you will never get a good set up. The same can be said for cartridges and tonearms. Its all about matching tone arm mass and cartridge compliance. And as to the phono pre, its all about selecting the one which can deal with resistence or compliance issues presented by the cartridge. Ditto I/C's. To change any single one of the basic components requires some research to get it done right. Thats why I recommended that the poster do some reading on the subject.
In passing, I find it interesting that the poster never stated what he found objectionable about his present system, just that he wanted to improve it. Personally, I don't think he will get the improvement he is seeking by just changing his cartridge (which is a fairly good cartridge), in the dark so to speak, unless he can articulate how he wants to improve his system and what he finds lacking in his present set up.
