First thing, check the overhang and mount hole alignment. If that is perfect, be sure you have the proper resistance load for the Helikon. I have not experimented, but bet it is well below 47K, probably near 22K.
Next, lower the VTA to a few degrees below level at the rear of the Graham arm. This may be as much as one fourth of an inch, must be determined by ear. This should clean up the highs and improve bass. You turntable must be absolutely level, the Graham hates being out of level.
Set tracking at heaviest setting suggested by Helikon, check cartridge centering and parallel alignment within the Graham head shell, and be sure the suspension system is free of any encumbrances. The azimuth is critical as well, set a red sable artists brush gently against the side weights of the Graham to hear changes while listening. This is dangerous if you lack the delicate touch, obviously do not try it if you have concerns.
Let us know how the experiment goes.
On break in, probably minimum of 100 hours.
