Ortofon FF15XE MkII already installed. and i had no problems with it while setting the force to about 1.5g. the cartridge was just old and sounded pretty bland that's why i decided to upgrade. but, oh well.
But the AT440 you have has a superior Fineline stylus, like the VMS30 in that Ortofon list which is just that bit harder to align. Once you get it right though it should be very quiet and the most detailed type of stylus available.
Start with getting the table levelled. Turntable Basics. Turntable Belts, Parts and Accessories. sell a good miniture spirit level, although you will probably find one these cheaper in a model shop if there is one nearby. BTW they also sell a good alignment protractor which is mirrored and makes this a much really simpler task.
If the table isn't perfectly level your adjustments to the tonearm won't be effective as it's also got to work against gravity remember.
Also when you line up the cart the stylus tip's got to be on the exact spot indicated on the protractor as well as having the cantilever parallel to the lines otherwise the overhang distance is wrong.
when you are happy with this then you zero balance the arm with the antiskate also set to 0 and then dial in the downforce to the max recommended.
Then set the antiskate by increasing it gradually until the cart will rise and fall into the same groove when with cued with the lever.
